My Sony Vaio NSE laptop with vista premium appears to have a usb port falure with my Microsoft Mouse built in web cam and keyboard I use. "USB device not recognized" keeps appearing. I tried the devices on another computer, and they work fine. I have rebooted and even system restored, and continue to not have my devices installing. I was not actually even active on the computer, when this appears to have occured. have run all the traditional security scans as well.
