If your device is not recognized at the moment, you can try the below six solutions to make it show up again. You don't have to try every method, but we strongly recommend you follow the sequence, which our experts have tried many times.
Fix 1. Unplug your computer to fix the USB device malfunctioned
It sounds like a piece of cake thing to do, but it works! For most of not recognizing USB gadgets, there is typically nothing wrong. A computer restart could solve it. This way is meant to reboot the motherboard, which has all of the computer hardware connected to, including the USB ports. Rebooting the motherboard usually helps solve the temporary insufficient power supply for outside devices.
Step 1. Cut your computer power at its source, which is unplugging your computer from the wall outlet.
Step 2. Leave the computer alone for a few minutes, and then replug it in the wall outlet for a restart.
Step 3. Now check if the computer is able to detect the USB device and assign a drive letter to it.
If this fix failed, don't panic, the next methods are also doable.
Fix 2. Change the USB cable or USB port to Fix USB device not recognized
Is the computer's USB port working properly? You need to check the available USB ports one by one to see whether it is a computer hardware problem or a problem with the device itself. If changing to another port solves the problem, then there is something wrong with the previous port. You can give up that broken port, or send your computer for repair.
Fix 3. Update/Rollback a device driver if the USB device not recognized
Device Manager operation is another widely suggested way to troubleshoot a non-recognizable USB device on Youtube and IT forums. Does this method apply to your situation? Go on to have a check.
Step 1. Type device manager in the search box to open Device Manager.
Or you can press Windows + R keys simultaneously to bring up the Run box, then type devmgmt.msc, and hit Enter.
Step 2. Expand "Universal Serial Bus Controllers" and you will see the item called "Generic USB Hub". Righ-click on the first Generic USB Hub and choose Properties.
Step 3. Now, navigate to the "Driver" tab, choose "Update Driver...".
Step 4. When asked how do you want to search for driver software, there are two options.
1. Search automatically for updated driver software
This way is an automatic update by Windows. When it finished, all you need to do is to disconnect the USB device, restart the computer and reconnect it again. Windows will install the latest driver for you.
2. Browse my computer for driver software
When you choose this option, you need to continue with the other pop up "let me pick from a list of device drivers on my computer."
From the list, select Generic USB hub, which normally the only choice. Click "Next" and then Windows will install the driver for you.
- If updating the driver doesn't help solve the USB device problem, don't suspend though, try to update each Generic USB Hub until updated them all for once.
In the same path to update the driver, you can also try to roll back to the previous driver before the error occurs. Instead of selecting "Update Driver" in the "Driver" tab, choose "Roll Back Driver" this time.
The changes made on the computer power and the device driver should take effect, and your USB device will no longer report issues. Otherwise, try the rest three methods one by one.

Frequently Asked Questions
- 1. Why choose EaseUS Data Recovery Wizard?
"EaseUS Data Recovery Wizard is the best we've seen. It's far from perfect, partly because today's advanced disk technology makes data-recovery more difficult than it was with the simpler technology of the past, but it's fast and efficient..." —PCMag

You won't find lots of extra options hidden in a system of hidden menus, either; what you see really is what you get." —techradar
"Recover lost files, even after deleting a partition or formatting your drive." —Macworld
- 2. Why cannot I recover 2GB data for free?
It is recommended to check the version installed is Free or Trial because they are different versions.
Trial has data preview function but cannot save any files, while the Free version enables to recover 2 GB files. The default free space is 500 MB and you may share the product on social media to get another 1.5 GB.
- 3. Why cannot the recovered files be opened?
A file is saved as 2 parts on the storage device: directory info (which is comprised by file name, time stamp and size info, etc.) and data content.
If the files with original file names and folder structures cannot be opened, one possible reason is the corrupted directory info. There is still a chance to recover the data content with the RAW Recovery method in our software.
- 4. Why isn't it suggested to recover the files back to the original drive?
The storage structure of the lost files would be altered or damaged by any changes on the drive. If you save the recovered files back to the same drive, the original data structures and data content would be corrupted or overwritten, which causes permanent data loss. So you should prepare another disk to save the files.
- 5. How can I check whether my data is recoverable or not before purchase?
The Free version helps you save 2GB files, so verify the recovery quality of our product before purchase.
- 6. How long does it take to scan the drive?
It strongly depends on the capacity of your hard drive and the performance of your computer. As reference,most drive recoveries can be completed in around 10 to 12 hours for a 1-TB healthy hard drive in general conditions.
