How to connect an Android device to a computer with USB Mass storage mode. Connecting a flash drive to a smartphone: Four ways (plus bonus)

You can enable USB ports on a laptop through the BIOS, Device Manager, Registry Editor, or Group Policy Editor. If access to the USB connectors was intentionally prohibited using special software, then you can unblock it in a program where the interface is blocked. All methods are available to ordinary users and do not require special training.

Disabling unnecessary devices

If the USB ports suddenly stopped working and you are now looking for how to turn them on, then the first thing to do is look to see if the device is connected to the laptop too much. When using a USB hub, the laptop may not be able to supply power to all devices, causing the USB ports to become unresponsive. Before setting up USB in the BIOS, unplug any unnecessary hardware from your laptop and check if the ports work. If nothing has changed, then reboot the laptop and go into the BIOS.

Enabling ports in BIOS

To enter the BIOS during boot, press Delete, F2 or another key depending on the motherboard model. You can view it on the start screen.

In the case of a laptop, this screen does not appear because the fast boot feature is activated. You can temporarily disable this technology in the power settings:


Restart your computer. Without Quick Start, you will see all stages of Windows boot and can get into the BIOS. If this doesn't work on Windows 8 or 10 with UEFI BIOS, try the following method:


Once rebooted, select Diagnostics, then go to Advanced Options and open UEFI Firmware Options. Click "Reboot", the next time you start, the BIOS UEFI interface will appear.

To configure USB ports in UEFI, you need to go to the “Peripherals” tab and set the “Legacy USB Support” parameter to “Enabled”. If support for USB 3.0 ports is required, activate the corresponding item (USB 3.0 Support).

In the AMI BIOS, go to the “Integrated Peripherals” section and set the four options to “Enabled”:

  • USB EHCI Controller.
  • USB Mouse Support.
  • USB Keyboard Support.
  • Legacy USB Storage Detect.

In Phoenix AwardBIOS, you need to go to the “Advanced” tab and go to the “USB configuration” section. All parameters inside must be set to “Enabled” for the USB ports to work.

In all BIOS versions, to save the configuration, you must press the F10 key and confirm the selection by writing “Y”.

Windows setup

If ports are enabled in the BIOS, but devices connected via the USB interface are not detected by the system, then check the registry editor, device manager and group policy editor. It is possible that changes were made to the system through them, due to which the ports are no longer working. You should start with the Registry Editor.


If USB support is enabled in the Registry Editor, check the controller drivers in Device Manager.


If you see an exclamation mark icon next to the controller, and you are sure that the interface is supported in the registry editor, then this means that there are problems with the drivers. First try updating the software:


If updating the controller software does not help, update the motherboard driver. Download it from the manufacturer's website and install it manually. Another way to update the drivers of all controllers at once is to remove them from the system. Right-click on the controllers and select "Delete". After a reboot, the system will automatically install controller drivers, so you no longer have to worry about how to enable the USB ports - they will work just like that.

If only removable devices connected via USB do not work, check in the Group Policy Editor to see if a read ban is set.


Find the Removable Devices: Deny Read option and set it to Disable. The problem with identifying flash drives and external drives should disappear.

Hardware damage to ports

If the laptop's USB ports or the south bridge on the motherboard are damaged, then no methods will help enable the interface. Therefore, if the connectors stop working after mechanical impact, liquid getting inside the case, short circuit or other negative factors, then you should take the laptop to a service center for diagnostics.

Despite the support of an Android smartphone or tablet for SD cards up to 32 GB, sometimes you need to connect external “storage” - portable hard drives and flash drives.

The essence of the problem with USB-Flash drives on Android devices

Modern Flash drives have a capacity of up to 128 GB. This amount of memory is not superfluous, especially when the owner of a smartphone or tablet downloads and distributes many films, music, programs, etc. at once. Additional memory is needed. The essence of the problem is as follows.

  • You cannot install more than one SD card in each gadget - these are not SIM cards; there is only one slot for an SD card in a smartphone or tablet. Devices with two microSD slots are a big question. There are also no memory cards with a capacity of a terabyte or more; all this is a matter of the future.
  • It is not always possible to transfer your content from your device to the cloud and back: mobile Internet is not completely unlimited, and searching for Wi-Fi around the city or “tethering” to a router with Internet from Rostelecom at home and at work is also not an option.
  • Continuously exchanging tens of gigabytes of traffic per day over cellular networks and Wi-Fi, a smartphone or tablet consumes a lot of energy. To recharge the gadget, you need an outlet or a powerful PowerBank with a battery with a capacity of 10 ampere-hours or more. In general, you need to store all your “pumped up” stuff somewhere, while still remaining mobile and free to choose.
  • For this you need to connect additional “flash drives” via microUSB. An ideal option for those who often go on business trips or travel is to carry a tablet and several 32–128 GB flash drives in your bag.

    How to connect a flash drive to an Android gadget via OTG

    OTG is a USB-microUSB adapter, a replacement for a USB cable with a Card Reader device. Takes up little space - no more than a standard flash drive. In this case, the flash drive must be formatted in FAT32 - not everything is going smoothly with the NTFS file system for the Android operating system.

    There is a more difficult way: install a special Android application that allows your smartphone or tablet to work with NTFS media. So, these can be exFAT/NTFS for Total Commander, Paragon NTFS & HFS+ and their analogues.

  • The OTG adapter must have a USB connector for a flash drive plug. This is exactly what you need. Most modern Android devices do not have a miniUSB connector, but a microUSB connector. Find an OTG adapter of the required standard in the store. The OTG adapter is available both as a solid device and as a special microUSB cable.

    You need OTG with a socket, not a plug for USB drives

  • After connecting the flash drive, launch the “File Manager” on your device - its contents should be displayed at the address ‘/sdcard/usbStorage’.

    Select the USBdisk folder

  • If the flash drive is not readable, you need special Android applications. Some of them require Root rights.

    How to get Root access

    Applications that allow you to get Root access without using a computer: FramaRoot, Universal Androot, Visionary+, GingerBreak, z4root, BaiduRoot, Romaster SU, Towelroot, RootDashi, 360 Root, etc.

    Applications that “hack” Root via PC: SuperOneClick, Unrevoked, GenoTools, vRoot, MTKDroidTools, etc.

    Remember that by obtaining Root rights, you lose the supplier’s warranty and risk harming your gadget.

    Another way is to change the licensed Android firmware to a “custom” one with unattached Root access.

    Viewing the contents of a flash drive on an Android smartphone or tablet using third-party applications

    USB Media Explorer app

    If you want to simplify the process of accessing a flash drive, use the paid USB Media Explorer application. The old name of the program is Nexus Media Importer; it was initially developed for Nexus gadgets, but quickly expanded the line of supported Android smartphones and tablets. Root rights are not needed, the program is paid.

    If this solution doesn’t suit you, you’ll have to work a little harder.

    Solutions based on the StickMount program

    The StickMount application is one of the most famous and requires Root rights. Works in conjunction with any Android file manager, for example, ES Explorer. Both applications are available on the Play Market.

  • After installation, open StickMount, connect your flash drive and confirm the request to autostart StickMount when connecting flash drives.

    Confirm your request

  • The second request will be the StickMount application asking about Root privileges in the Android system. Confirm by clicking the Grant button. Do not check the box next to “Ask me again in the future.”

    Confirm by pressing the Grant key

  • A warning will appear in the notification bar (at the top) that the contents of the flash drive are located at '/sdcard/usbStorage/' - now open the ES Explorer application.

    Displaying information about the load on the flash drive

  • The flash drive is read/write.

    All your files are now available

    Connecting USB flash drives to devices that do not have miniUSB/microUSB

    A number of companies, not as well-known as ZTE, Huawei, Sony and their other competitors, install non-standard interface connectors. OTG adapters with miniUSB/microUSB are absolutely not suitable for gadgets with a highly standardized connector without a special OTG adapter. Look on Ebay or AliExpress for an OTG adapter that matches the standard of the interface socket of your smartphone or tablet. Further steps to obtain software access to your flash drives are the same.

    Other ways to connect a flash drive to an Android smartphone or tablet

    There are the following methods:

  • Connect both the tablet/smartphone and the USB flash drive to the PC.
  • Connect the flash drive to your smartphone/tablet through a special device - CarsReader. Suitable for owners of SD/MiniSD cards, USB MemoryStick flash memory.
  • Connecting a microSD memory card through a special adapter that has a USB plug is similar to a regular USB flash drive.

    How to connect Android to computer. Many users of mobile devices running the Android operating system complain that they cannot connect their gadgets to a personal computer in storage mode (external USB drive).

    Unfortunately, it is not possible to give the only correct solution to this problem. The thing is that smartphone and tablet manufacturers not only use the Android system as the main platform for their own applications, but also significantly modify the initial set of “green robot” options.

    In any case, there are no hopeless situations. So, let's start dealing with the problem from the very beginning. The ideal situation is when, when you connect your Android gadget to your computer, you see something like this:

    This means that your mobile device is recognized by the computer as a virtual flash drive and is ready to connect. In the additional connection menu you should expect a similar picture:

    Click the “ Enable USB storage" And after that, “big brother” is simply obliged to give you a pop-up window describing options for working with an external drive (device memory):

    If this does not happen, then:

    1. Paradoxical as it may seem, the first thing you should do is check the cable with which you are trying to connect your smartphone (tablet) to a personal computer. Don't ignore this step! Carefully inspect the connecting cord for breaks and abrasions. If there is such a possibility, then try to establish a connection with the computer using a different, but definitely similar, cable.

    Are there any visible problems with the physical state of the elements of the future connection? Then move on to the next step.

    2. Try changing the device’s operating mode in the device connections menu. In this case, the mobile device must be connected to the computer! For example, as indicated in this screenshot:

    It often happens that mobile device manufacturers save on developing their own drivers, using universal drivers by default. Therefore, it is possible that after connecting several gadgets to the same computer, the desktop operating system does not perceive the new smartphone or tablet correctly.

    If at this step Windows begins searching for and installing the missing drivers, then you are moving in the right direction:

    Once the device initialization process is complete, a similar message should appear:

    Did not work out? A similar process has not started on your computer? Then we advise you to complete the next step.

    3. Without disconnecting your mobile device from your personal computer, turn USB debugging on and off several times. This will help the Windows operating system identify the gadget's internal storage as a new (recently connected) device.

    In this case, a pop-up message with approximately the following content will most likely appear on the desktop of your desktop computer:

    If, after performing the steps described above, the virtual USB device is not recognized, then it’s time to move on to “street magic”.

    4. At this step, you will have to check the drivers installed on the desktop system and the items that appear in the device manager after connecting the gadget.

    So, open this same device manager:

    We carefully review the list that appears. What you should be primarily interested in is not the auxiliary modes of operation of the mobile device,

    and subparagraphs “ Disk devices

    or " Portable devices”:

    If new lines appear in the device manager, but do not correspond to the type of connected gadget (differences in name, model, etc.), then using the context menu

    and reinstall existing drivers:

    The files you need can be easily found in the appropriate section of the website of the smartphone or tablet manufacturer.

    Well, that's the last resort. It’s worth going to it only if, after completing the previous steps, you still weren’t able to switch your gadget to USB storage mode.

    In the main window, carefully analyze the item “ Disk Management" Has a virtual flash drive appeared there? Is its size determined correctly? Has Windows assigned the correct volume letter?

    In most cases, this is the root of all troubles. If in the disk tree you see the internal memory of your gadget, but its mount point is incorrectly set, then using the context menu, simply replace it with the one you like best:

    We hope that after strictly following the paragraphs of this instruction, you will be able to easily work with the files of such a dear gadget to you

    and a similar message will greet you every time after connecting your smartphone (tablet) to a personal computer.
