Recovery: Rescue Data from the Unknown USB Device
Whenever you meet the unknown USB device issue, you are advised to recover data from the unknown USB device at first. When the data recovery has been finished, you can try every possible means to fix the problem (this is for data security reasons).
USB Device Data Recovery Plan
Step one: if you envy the free USB data recovery, please get the following trial edition and install it on your computer properly.
Step two: connect the target USB device to your computer and launch the software you have just installed by double clicking on the icon.
Step three: shift to the Removable Disk Drive option from This PC (checked by default). Then, take a look at the right panel to see whether your USB device appears here.
- If it does appear, please select it and click on the Scan button to start searching for files saved in it.
- If you can’t find your USB device, please try to fix the problem & make it appear here after reading Fix USB Flash Drive Not Recognized & Recover Data – How To Do.
Step four: wait for the scan. Then, browse all the files and folders found & listed by the software to figure out whether they contain the lost data you need.
- If you have found the documents you want, please check them one by one.
- If not all your needed files are here, please wait patiently for the completion of the scan (to get the best recovery result).
Please note that:
- You can choose to Pause the scan when you have to leave for a while and don't want the scan to continue.
- You may as well click on the Stop button to cancel further scans completely when you have found all the files you need in the current scan result.
Step five: click on the Save button located in the lower right corner of the software interface. Then, choose a storage path for the selected files (which are waiting to be recovered from the USB device) and click on the OK button to reconfirm your choice (this step can’t be accomplished if you are using a trial edition to scan the USB drive).
To really recover the needed data from the software scan result, you should:
- Get a license key.
- Register your copy of software with that license.
- Re-scan the USB device and check files to recover.
This is the end of data recovery from an unknown USB device. Actually, the method also works for the situations where you need to recover deleted files from USB drive or fix a broken USB stick.

Repair: Fix the Unknown USB Device Issue in Different Ways
As I said earlier, the USB port has been applied to a lot of commonly seen products, mobile phones, USB flash drives, printers, scanners, tablets, laptops, and desktops. You need to connect the USB device to a computer to deal with some data copying, managing and transferring work most of the time.
This is where the problem comes in – an error of Unknown USB Device is given by the Windows computer (and the computers running Linux or other systems). Well, what are you going to do when encountering the following error messages?
- Unknown USB device (device descriptor request failed) nothing plugged in
- Unknown USB device (port reset failed)
- Unknown USB device (the device failed enumeration)
- Unknown USB device (set address failed)
- Error code 43

Please check whether the USB port is damaged or not when you see those error messages: try connecting it through other USB ports on the computer or try to connect it to a different PC. Then, shut down your computer, restart it, and plug the USB device into a good USB port to see whether the problem can be fixed.
If this fails, you should connect the target USB device properly to the computer and then resort to the following workarounds yourself (all steps are finished in a Windows 10 computer).
Workaround 1: Check & Repair Bad Sectors
If bad sectors appear on a USB storage device, the corresponding area can’t be read or written.
How to check and repair:
- Launch MiniTool Partition Wizard to enter its main interface.
- Select the USB disk from the right pane and choose Surface Test from Disk menu (you can also select the USB partition and choose Surface Test from Partition menu when the USB device contains only one partition).
- Click on the Start Now button in the pop-up Surface Test window and wait for the check process.
- Take a glance at the result and decide what to do next (if there are only a few bad sectors, you may try to repair them; if too many bad sectors are found, you’ll need to discard this device and buy a new one, for the sake of data security).
- Repair the bad sectors with special tools when necessary.
Workaround 2: Use Hardware and Device Troubleshooter
Troubleshooter is actually a universal troubleshooting tool built-in in the Windows systems. It works well in checking and repairing many common system problems.

Workaround 3: Uninstall/update the USB Driver
The problematic USB driver (the driver is outdated, corrupted, broken, or missing) is likely to be the cause of the USB device descriptor failure issue.
How to uninstall/update:
- Open Device Manager the way you like (type msc in Run or right click on This PC & choose Manage & select Device Manager).
- Find and expand Universal Serial Bus Controllers from the right pane.
- Now, you can locate the malfunctioned USB drives easily (they are marked with a yellow triangle, with an exclamation point inside).

Yet, some people complained about this: the fast startup generates an ultra-fast execution speed so that the USB device may not be detected by Windows 10 or other systems; thus, the USB device descriptor failure may appear.
Now, I’ll show you how to fix the error by disabling fast startup:
- Open the Run dialog box by holding the Windows key and R key on the keyboard at the same time.
- Type control/control panel into the text box after the word Open:.
- Press Enter on the keyboard or click on the OK button in the Run dialog box to open Control Panel.

If you’re having issues connecting a Bluetooth device to your computer, there are a number of troubleshooting steps you can do on Windows 10.
In this guide, you’ll learn the steps to fix a number of connection problems with Bluetooth devices on your Windows 10 computer.
How to fix Bluetooth missing in Settings
When you’re in Settings and you don’t see the Bluetooth page, it’s possible that something is wrong with the Bluetooth driver or your device doesn’t include support for this kind of connectivity.
If there is support for Bluetooth on your device, you can use Device Manager to see if the latest driver is installed.
Open Start.
Search for Device Manager and click the result.
Expand Bluetooth.
Right-click the Bluetooth adapter, select Update Driver Software, and click Search automatically for updated driver software.
In the case the operating system can’t find any new driver, you can visit your computer manufacturer’s website to download the latest driver and instructions to complete this task.

Once your computer rebooted, go back to Device Manager, and if you still don’t see Bluetooth listed, click the Scan for hardware changes button on the top-right. If the operating system still can’t detect the device, manually download and install the Bluetooth device driver from your manufacturer’s support website.
How to fix Bluetooth after upgrading to Windows 10
In the case, you just updated to Windows 10, and your Bluetooth device is not working, it could be that the device uses a custom Bluetooth profile.
If this is the problem, you’ll need to remove and reconnect the Bluetooth device again to resolve the issue.
Wireless devices to work on Windows 10 must use one of the supported Bluetooth profiles:
- Advanced Audio Distribution Profile (A2DP 1.2)

- Human Interface Device (HID 1.1)
- HID over GATT Profile (HOGP 1.0)
- Object Push Profile (OPP 1.1)
- Personal Area Networking User Profile (PANU 1.0)
- Serial Port Profile (SPP 1.2)
In order to figure out what profiles your Bluetooth device supports, you’ll need to check your manufacturer’s website for documentation.
How to fix Bluetooth device connection when paired
When your device is paired, but it’s not working, you can use the following steps to fix the problem:
Open Settings.

Once you completed the steps, you’ll need to connect your Bluetooth device again using these steps.
If the device you’re trying to connect doesn’t include a display, but it needs a PIN to pair, you can check the device or documentation to find out the PIN. However, most of the time, the default PIN is just “0000” or “1234”.
