Recovery: Rescue Data from the Unknown USB Device

Download Driver Usb Device Descriptor Failure

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).

Warning: According to a survey, lost/damaged data can be recovered to a great extent. But why there are many cases where these data can't be restored completely? In fact, more than 90% of the failure is caused by incorrect operations during the recovery process, resulting in greater damage. So please keep the following suggestion in mind if you have no idea of how to do data recovery: after data loss, shut down the computer immediately, and avoid any operation to the hard drive; otherwise, it will increase the difficulty of data recovery.

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 theRemovable 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.

As for how to recover data from the HDD which shows as unknown, you should read this post carefully:

On discovering your disk shows as unknown, uninitialized or unallocated, you must take actions at once to recover all valuable data from it.

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).
