It will just turn off the computer, and the motherboard will be still in power supply. So, turn off the system and unplug the power supply cable. Wait for a while. Connect the USB device to your system and turn on the system. Now plug-in the power supply cable.

There are some more options to do for the users. If the above-discussed solutions do not work for you, try these common methods.
Method # 9: Run an Antivirus Scan
It may be due to a malicious virus or malware in your system. You need to run an antivirus scan to remove this error.
Download a certified antivirus program from a trusted site and run its scan to fix the error. I would recommend you to use AVAST antivirus that is easy to install and a user-friendly tool.
Method # 10: Remove the Battery
If you encounter this error, just turn off the system and remove the battery from the system (If you are using the laptop) Now wait for a few minutes. Reinstall the battery and turn on the system.
See if it fixes the error.
Method # 11: Clean the RAM
A dusty RAM can cause creating errors for you. Just turn off the system. Remove its RAM and clean the dust from it to bring it in working condition.
Now install the RAM into the system and turn on the system. I am sure you will not see the “USB Device not Recognized” error again.
Q: I don’t connect any USB device to the system, but still it shows this error “Device not Recognized.”
Ans: If you see this error without connecting any USB device to the system, it may be some other hardware device of your system whose driver is missing or corrupt. Probably, it is the card reader device or fingerprint reading device in your system that is causing this error.
Open “Device Manager” and see if there is a yellow sign on any other device. If it is so, just update its driver to fix the error.
Now reboot the system and check if the error is fixed.
Q: Whenever I attach the USB mouse with my system, it shows this error. It is entirely frustrating. The above-discussed solutions solved my problem temporarily.
Ans: Your device is creating an error. Scan the system by using an “Antivirus program.” If the error persists, change the USB device you try to connect.
Q: I use a USB device with my system, and it shows an error message. But when I plug in the same USB device with any other system, it does not show the error message.
Ans: It looks weird but a working solution. If you unplug the USB device directly, it may show error when you use it the next time. You need to attach the USB device to another computer and unplug it by using the proper way.
Go to the “Notification Tray” and right-click on the USB device icon. It will show you the “Eject” option. Just select this option to remove the USB device from the system safely. Now remove it from that system and connect to your system, it will not show error this time.
