Remix OS for PC beta: how to organize dual-boot with Windows and start working with the new OS. We use the WinToFlash program

USB technology is one of the most important of the many technologies that have had a huge impact in computer world. USB (Universal Serial Bus- “universal serial bus”) - serial interface data transfer for low- and medium-speed computer peripherals

This technology has made it truly easy and convenient work with printers, scanners and external devices data storage (external hard disks, USB flash drives). All actions with USB installation devices have been reduced to simple principle « Plug and play" Devices have become truly mobile precisely because of USB technology. Today, not only desktop PCs and laptops are equipped with USB ports, but also gaming devices, smartphones, cameras, navigators and many other devices.

Ports USB version 2.0 provide data transfer at speeds up to 480 Mbit/s, and the version USB 3.0 raises the maximum transfer speed to 5.0 Gbps. The USB symbol is a kind of trident, drawn as in USB devices oh, and on computer connectors.

Technology USB already has been studied quite seriously and has undergone many improvements, so USB ports, when used correctly, rarely cause any problems, and troubleshooting problems associated with them does not cause much trouble. This article will outline the basic principles of troubleshooting USB ports.

But before we begin, it’s worth describing basic recommendations when working with USB ports and devices, connected to them:

- never connect devices with visible mechanical damage USB connectors, as well as devices with external damage to the housing or with a clear burning smell.

If on the mother's USB board ports have mechanical damage, then it is better to disconnect them from motherboard(connectors on the front of the case) or cover with colored tape to prevent their use. If necessary, it is better to replace such ports in a workshop with new ones.

Try not to overload USB ports. Their current strength is strictly limited: 500 mA for USB 2.0 and 900 mA for version 3.0. Do not strive to increase the number of USB ports using various USB multipliers. Modern motherboards already have up to 10 ports, which is quite enough for home use. It's always safer to buy additional PCI or PCIe USB controller than working through a USB “tee”.

If the USB ports on a laptop stop working, then working on it becomes very difficult - you cannot connect a printer, a scanner, or a flash drive. And unlike desktop computer, installation additional USB The controller is a very expensive pleasure.

In many cases, when the error message " USB device not recognized "The problem may be in the USB port. This problem is usually solved quite easily, since it occurs mainly at the software level.

What to do if the USB ports do not work?

Any hardware device interacts with the installed operating system through special program - driver. Many problems with devices are solved with the help of drivers. The same is the case with non-functional USB ports. Below are a few ways to help you resolve USB fault ports at the software level.

If the USB ports suddenly stop working, and USB devices are not detected, then the most in a simple way The solution to this sudden problem will be to restart your computer. Just restart your computer. If there were no problems loading the drivers, this problem will be resolved after a reboot.

Update hardware configuration in Device Manager

If you restart your computer in this moment is not desirable (for example, due to performing some important operation), then you can “reload” the drivers without rebooting the entire computer via device Manager. To launch it on the shortcut " My computer» click right click mouse and select the menu item " Management e". Or in the menu " Start» find the program « Execute"and after launching it, enter the command devmgmt.msc.

In the window that opens, left-click once on the list of devices and then click the tab " in the main menu Action", then point to " Update hardware configuration" See if the section " USB controllers" If yes, then your problem is solved, the USB ports should work.

Another way to get USB ports to work is to unplug and then reinstall the USB controller. To do this you need to run again device Manager. In the list of equipment that you will see in the window that opens, find the USB controllers section. On each of the devices in this section, right-click and delete them all. Once you remove all controllers, simply restart your computer. The controllers will be reinstalled and the USB ports will become available again. This may solve your problem.

Updating USB controller drivers

Another reason that USB ports do not work is damage to the USB controller drivers. The only way out is to find the correct drivers and reinstall them. To download the appropriate driver, you need to find out the manufacturer of the USB device port (via it). Installation correct driver should solve this problem in an instant.

Disabling other USB devices

Sometimes USB ports do not work due to overload when too many USB devices are connected. USB hubs sometimes do not provide enough power to the devices connected to it. The connected device can consume all the permitted power of the computer's USB controllers. If the equipment is connected to a USB hub, then simply connect the device directly to a USB port on your computer.

You can also leave the device connected to the USB hub, but first disconnect other devices in the hub. For the future, purchase a USB hub with its own power supply that will provide sufficient power to all devices connected to it.

If none of the above methods worked, then it is likely that the USB ports were physically damaged. Or the USB controller is damaged, in particular south bridge motherboard. In this case, the best thing you can do is replace or repair the USB port controller at a service center.

Back in 2008, the 3rd version of the world famous USB standard was finally approved. Engineers from companies such as Intel, Microsoft, HP, etc. worked on its development. It was important that new standard remained compatible with old usb 2.0. All connected devices worked exactly the same as with the old standard. But the connection capacity has increased significantly. Now it was possible to transfer not 600 megabytes per second to maximum speed, and up to five gigabytes per second. Also, the current increased to 900 milliamps.

By the way, these USB connectors there is a whole bunch, so look at the photo above and remember what they are like.

How to install usb 3.0 on a computer

It seemed to everyone that within a few months the new device would appear, and the process of copying files would be ten times faster. I wanted flash drives and everything to work much faster. But Intel refused to introduce USB 3.0. to your 2011 devices. The standard was released, but there were no actual physical motherboards with integrated USB 3.0.

But on the market computer devices new devices appeared that made it possible to work with USB interface 3.0. Naturally, motherboards with such a controller appeared, but they also cost much more than similar analogues without the corresponding connector. In this case, what was invented to work with new usb standards?

So, many craftsmen realized that there is. This port provides very high throughput compared to usual USB ports. Any motherboard has PCI express. It is this connector that graphic card manufacturers began to use.

Now the only thing left to do is to translate PCI Express to the transfer function USB data 3.0. To do this, you can go in two ways - solder the corresponding adapter yourself, or buy a special adapter in an online store, ready for use and providing a USB 3.0 standard signal at the output. The second method is the least labor-intensive and therefore users began to buy such boards. Here is an example of such a board - you plug it into PCI and USB output 3.0

However, over time, minor shortcomings of this connection were discovered. For example, it is very inconvenient when the connectors of the new USB 3.0 are located behind the case. Many system units are installed so that access to the rear of the case is limited. Therefore, you need to transfer the USB pins to the front side of the case. In this case, you need to buy the corresponding USB expansion board kit.

Another disadvantage of such a board is that one PCI Express can be occupied by the video card. But the other slot has a reduced speed, which the user may not even suspect. That's why

You need to install such an expansion card only with full confidence that the slot will work at full power, otherwise you will still be working with the same USB 2.0.

USB (Universal Serial Bus or Universal Serial Bus)- the most multifunctional port to date. Using this connector, you can connect not only a flash drive, keyboard or mouse, but also many other devices to your computer. For example, there are portable mini-fridges with USB connection, lamps, speakers, microphones, headphones, Cell phones, video cameras, office equipment, etc. The list is actually huge. But in order for all this peripherals to work properly and data to be transferred quickly through this port, it is necessary to install drivers for USB. In this article we will look at an example of how to do this correctly.

By default, USB drivers are installed along with the motherboard software, as they relate directly to it. Therefore, if for some reason you do not have installed USB drivers, we will turn primarily to the websites of motherboard manufacturers. But first things first.

In the case of USB, as with any other computer components, there are several ways to find and download necessary drivers. Let's look at them in detail in order.

Method 1: From the motherboard manufacturer's website

First we need to find out the manufacturer and model of the motherboard. To do this, you need to follow a few simple steps.

On the button "Start" you need to right-click and select « Command line» or "Command Prompt (Administrator)".

If you have installed operating system Windows 7 or below, you need to press the keyboard shortcut "Win+R". As a result, a window will open in which you need to enter the command "cmd" and press the button "OK".

In both the first and second cases, a window will appear on the screen "Command line". Next we need to enter following commands in this window in order to find out the manufacturer and model of the motherboard.

wmic baseboard get Manufacturer - find out the board manufacturer
wmic baseboard get product - motherboard model

Now, knowing the brand and model of the motherboard, you need to go to the manufacturer’s official website. You can easily find it through any search engine. For example, in our case it is ASUS company. Let's go to .
You need to find a search bar on the site. We enter the model of the motherboard into it. Please note that in laptops, most often the motherboard model matches the model of the laptop itself.

Pressing the button "Enter", you will be taken to the search results page. Find your motherboard or laptop in the list. Click on the link by clicking on the title.

In most cases, you will see several sub-items at the top. mother card or laptop. We need the line "Support". We click on it.

On next page we need to find a point .

As a result, we will be taken to a page with a selection of the operating system and the corresponding drivers. Please note that you may not always be able to see the required driver on the list. In our case, the driver for USB can be found in the section "Windows 7 64bit".

Opening the tree "USB", you will see one or more links to download the driver. In our case, select the first one and press the button "Global".
The download of the archive with installation files will begin immediately. After the download process is complete, you need to unpack all the contents of the archive. IN in this case it contains 3 files. Run the file "Setup".

The unpacking process will begin. installation files, after which the installation program itself will start. In the first window, to continue, you must click the button "Next".

The next point will be to familiarize yourself with license agreement. We do this as desired, after which we put a mark opposite the line "I accept the terms in the license agreement" and press the button "Next".

The driver installation process will begin. You can see your progress in the next window.

Once the installation is complete, you will see a success message. To complete you just need to press the button "Finish".

This completes the process of installing the USB driver from the manufacturer’s website.

Method 2: Using automatic driver update programs

If you don’t want to bother with searching for the manufacturer and model of the motherboard, downloading archives, etc., then you should use this method. For this method, you will need any utility to automatically scan the system and download the necessary drivers.

For example, you can use or . In any case, you will have plenty to choose from. Similar programs online today a large number of. Take for example the same one. ABOUT detailed installation You can learn about drivers using this program from our special lesson.

Method 2: Through Device Manager

Go to Device Manager. To do this, you must do the following.

Please note that this method is the least effective of all three. But in some cases it actually helps the system to at least recognize the USB ports. After such an installation, you must search for drivers using one of the two methods listed above in order to ensure that the data transfer speed through the port is as high as possible.

As we previously advised, for any force majeure situations, always save the most important and necessary drivers and utilities on a separate media. If necessary, it can save you a lot of time that will be spent on re-search software In addition, situations may arise when you simply do not have access to the Internet, and you will need to install drivers.

Became the first Apple iOS device who received the port USB Type-C.

After 11 years of existence of the mobile operating system, the company for the first time moved away from the proprietary port, installing an interface that was recognized in absentia as the 2018 standard.

A potential buyer will probably be interested in what can be connected to a tablet, the power of which exceeds not only most devices in its segment, but even laptops and computers.

A little technical

So, before you decide to buy iPad Pro 2018, there are some things to know.

Firstly, this is the only port on the tablet. Apple decided to rely on versatility and, as happened several years ago with the iPhone, the iPad lost its audio port.

In this regard, get ready to use an adapter for almost any device that you plan to connect to the iPad Pro 2018.

Secondly, the iPad Pro, unlike almost all Apple laptops (with the exception of the 12-inch MacBook), has USB Type-C version 3.1 of the second generation installed. There is no Thunderbolt here.

But this does not prevent the tablet from transmitting data at speeds of up to 10 Gbps. Simply put, you can connect 5K monitors to the tablet and broadcast at up to 60 fps.

But first things first. Let's figure out what can be connected to the iPad Pro and what the new one allows (for iOS devices) USB port-C.

1. Connect external monitors

Yes, this is exactly why, in principle, Apple integrated USB Type-C into a completely updated tablet. You can arm yourself with a USB-C cable, plug it directly into the iPad, and plug the other end into a corresponding DisplayPort-enabled monitor with a USB-C return port.

Considering that the iPad Pro there is support for HDR10, the quality of the broadcast picture will be very tasty.

Another question is what the iPad Pro will stream when connected. It all depends on the application and the efficiency of the developers.

For example, Keynote and Netflix support are fine - connecting a monitor expands the functionality of the tablet and interface. But when working with the vast majority of applications, you should keep in mind that external monitor With the iPad Pro 2018, it doesn't work the way you're used to seeing when connecting a display to a MacBook.

One of the unpleasant moments is the absence of such a cable included with the tablet.

And further. Although it supports 5K displays, the same display is not compatible with the 2018 iPad Pro. And all because of this monitor Thunderbolt 3, but the iPad Pro doesn't support it.

The USB-C monitor segment is still incredibly scarce, so it would be more advisable to use an adapter from USB-C to HDMI.

By the way, maximum resolution, which the iPad Pro can transmit via this standard(HDMI 2.0) is 4K at 60Hz. Support for HDR10 and Dolby Vision will depend solely on which adapter you choose.

There's even an option for connecting legacy VGA devices. The corresponding adapter is commercially available and is suitable for connecting projectors or archaic monitors.

2. Charge iPhone and other electronics

Immediately after the announcement, a joke flashed across the network about whose role could be played by new iPad Pro 2018.

Well, there is some truth in every joke, and the new product can actually charge other devices and accessories.

But, again, you will have to spend money on a cable from USB-C to Lightning for iPhone charging or buy USB-C -> USB-A (female) to connect any other gadgets.

A pleasant and somewhat strange moment. iPad Pro 2018 while charging produces 7.5 W power. And here is the complete one Charger, which Apple continues to add to its iPhone already more than 10 years, capable of only a current of 1 A, which at a voltage of 5 V corresponds to only 5 W.

By the way, on the Apple website there is even special cable for charging Apple Watch. With one USB side Type-C, on the other - a proprietary magnetic washer.

3. Import photos and videos

Alas, not quite what you thought. You can't take a flash drive or external HDD and connect it to iPad Pro to copy files. Or rather, you will only see photos and videos, having the opportunity to export them.

All because limited functionality iOS. By the way, many are sure that in the future Apple will release an update for iOS 12, in which iPad owners Pro 2018 will still be able to use external drives.

But that will happen sometime later. And now, after the purchase, you can only count on importing photos and videos from USB drives. To do this, you will need to open the Photos application, connect external storage and select "Import".

You can also connect cameras and import photos directly from them. Apple even has a special adapter for SD cards. But you will have to buy any accessory for importing pictures separately.

4. Connect external keyboards and wired Internet

In theory, you can connect a lot of USB accessories to the iPad Pro 2018 using the appropriate adapter. But iOS does not provide for the installation of any additional drivers.

Therefore, anything that supports Plug-and-Play will do, that is, it works without additional installations Software when connected to USB.

Wired keyboards will fit perfectly.

You can even connect to iPad Pro 2018 wired Internet. All you need is a USB-C -> Ethernet adapter. It's hard to imagine places where there is no Wi-Fi, but suddenly it will come in handy. Either way, the iPad Pro has this capability, so if you need a gigabit connection, consider purchasing this accessory.

A new item for setting up the connection will appear immediately after you plug it into USB Type-C this accessory. Magic, Apple, what can I say.

5. Speakers, microphones and MIDI devices

Of course, Apple is aware that the iPad Pro is chosen creative people, and there are many musicians among the fans of the device. Leaving this layer of users without audio accessories would be a stone in their own backyard.

Given that the 2018 iPad Pro no longer has an audio port, you'll have to use a $9 USB-C to 3.5 audio adapter.

To work in GarageBand and other sequencers you will have to use already USB-C adapter-> USB-A. This way you can connect MIDI keyboards and USB microphones.

Installed in iPad Pro 2018 USB-C port produces 7.5 W of power, which is sufficient for most audio accessories.

Geektimes has written repeatedly about Remix OS, a desktop OS based on Android. On March 1, a beta version of this operating system appeared, which is already quite possible to deal with. Generally speaking, this is a customized Android version, which looks and works like a full-fledged operating system for personal computer. It was first released in 2015, with minimal support for multiple devices. In January, the alpha version of Remix OS was released, the developers made it available to everyone, opening the ability to boot the system from a USB drive.

The beta version introduced dual-boot, with the ability to switch between two operating systems - Remix OS itself and Windows. You can install the operating system as follows: HDD, and on SSD, which provides enough high performance platforms. Currently, the Remix OS installer for PC supports Windows 7 and above. later versions this OS. A version for Mac should be available soon. If you're tired of the OS, removing it is even easier than installing it.

Updates now come regularly, over-the-air update support is built-in. There are other news, including the transition to Linux kernel version 4.4 for better compatibility with newer processors, support for 1080p video from YouTube and Netflix, work with USB drives volume up to 64 GB and so on.

What's missing? Support Play Store. Since Remix OS is not certified by Google, there is no default access to the market. But you can add it, more on that below. First, let's talk about installing Remix OS itself.

Don't want to install Remix OS on an SSD or hard drive? No problem. You can work with the operating system directly from USB flash drives, making it bootable. But still, the performance of the OS in this case will be lower than if you put it on an HDD or SSD.

How to install Remix OS on HDD or SSD

1. First we download latest version OS from here. There are 32-bit and 64-bit builds for the respective PCs.

2. Unpack the archive and get three files: a text book with instructions, an installer and an ISO, a disk image.

3. Run Remix OS Installation Tool.exe and check that the installation location is correct (drive letter, etc.).

4. Click Next and select the disk image that was just downloaded. It will be something like Remix OS for PC_x86_64-B2016xxxxxx.iso.

5. Start the installation and wait a few minutes until a message appears indicating that you need to restart the PC to complete the installation.

Next step It will take from 15 to 30 minutes, depending on the performance of your PC. Remix OS creates its own 8 GB download area and installs the OS into this area.

8. Once everything is ready, Remix OS will boot for the first time and you can get started.

9. If you need to return to Windows, select the shutdown icon, then the reboot option. After that, instead of Remix OS on the selection screen, click on Windows.

How to install Play Store?

Everything is simple here. Here is a video describing the entire process:

Is it possible to get more than 8 GB?

The official Remix OS installer for PC takes 8 GB for its needs. This is enough for installation various applications, which you may need for work or entertainment.

But if you suddenly need more space, then it
