So i was trying to get my ps3 controller to work with my win 7 x64, installing some USB drivers.. when i rebooted, windows would immediately de-power all USB. nothing will even charge.. even in safe mode. I tried last known good config and nothin..
the devices work is BIOS and system recovery (win 7 cd in)
check your device manager more than likely your usb controller had a driver error from an update that go processed. if thats not the case then uninstall all the drivers for the usb hardware you have installed and then go from there
