USB devices detected and undetected in a cycle
Hi, recently, in my Win 7 32 bit SP1, USB devices like keyboard and mouse are getting undetected and detected every now and then. Troubleshooting shows "hardware changes might not have been detected". All the drivers are up to date. Sometimes the computer showed that there was a power surge in the USB hub. I think the USB hub is losing power every now and then! please help! i don't know, losing power is just my diagnosis!
