USB port gives new message "unknown device"


hello allan213

my name is ausi.

is it on all usb ports only one of them if it is in only one of them then the message you getting generaly means one of thw follwng.

1- if it is in only one of the ports then try it with a different device as well to see if it is the actual port or not.

2- the device you have plugged in needs to have drivers installed. normally should have been supplied with it.

3- the device you plugging in is faulty and the system can not access it.

4- the system usb ports are overloaded. (too many usb devices connected simultaneously)

good luck

Unknown Device


have you tried to plug it into another usb por to see if you get the same result, the original port might be in a locked state and may have had problems releasing the usb key.

Did you try reboot your PC?

Unknown device


Hi,
this is an error message stating that. the usb device is faulty.
It has detected that the usb port has an error/fault or problem.
check that non of the pins are touching each other, or that dirt or dust isn,t inside the usb connection port. blow in it. or use a cotton bud to swab it out.
