Problems with peripherals can happen suddenly. Yesterday your printer, mouse or keyboard was working fine, you turn your computer on today and boom – no printer, mouse or keyboard. In most cases, this problem is caused by driver issue. First of all, try to connect your faulty hardware to another USB port. Sometimes this helps to repair minor faults.
In a few cases, the problem is with faulty hardware. If none of your peripherals connected through USB are not working, this is probably the motherboard’s fault. If you have wi-fi printer and it is not working, this can caused by wrong drivers or wrong wi-fi router configuration.
