How to fix “Unrecognized USB device keeps popping up”?

Sometimes an improperly connected USB drive can cause such issues. So make sure it is properly connected to the USB port.

But if it does not work then continue applying the below mentioned fixes.

Disconnect external devices

If you have connected external devices, safely eject them and disconnect them from your system. Check if the error appears when you try to insert them. If you encounter the error message, the problem lies with the external device.

On the other hand, try changing the cable or adapter used to connect them to your USB port. Also try changing the USB port to eliminate any issues with it.

Connect devices to your system

If you have connected multiple devices to your system’s USB ports, your system may not be supplying enough power to each of them. So consider using a USB hub capable of supplying adequate power.

On the other hand, disconnect the devices connected to the USB hub and connect them directly to your system. Check if the error message still appears.
