7 Ways to Overcome USB Device Not Recognized/ Unreadable USB Windows 10,8,7
1. Restart the Device
Sometimes, a simple reboot can fix the USB Device Not Recognized device. Try restarting or shutting down your PC for a while, then try turning it on again.
Next, try to reconnect your USB device and see the results. If it still doesn’t work, try the next steps below.
2. Try on another computer
Try pairing your flash drive on another computer. If it still doesn’t work on another PC, then your USB is indeed a problem. Then there are only two options for you, buy another new one or try to repair it.
3. Remove another USB
Too many USBs on the same computer can also create conflicts that may hinder the device from functioning.
In order to avoid possible conflicts between the devices, it is recommended that you remove any other USB devices that were attached at the same time and see if the USB you want to use works.
