Windows 7 USB problem

palazzio

I have a Toshiba Satellite laptop running win 7 home which has 2 USB slots

Everything is fine when I only plug in one device eg mouse or flash drive. Whenever I add the second it loses the first device and does nor recognise the second one. I have tried it with both of the above in reverse order with the same result.

I have updated all of the OS and the drivers, uninstalled and reinstalled the ports without it making any difference.

Can anyone explain or suggest a solution???

Thanks in advance

Inspect the affected ports closely and see if their is any damage or looseness.
