I reinstalled win 7 ul x64 today and for some reason when I plug in a usb stick or external hard drive windows fails every time to install the drivers for it.Device manager shows code 10 device cannot start.When I boot my pc to the other windows 7 I have they all work fine.Its got to be a driver issue somewhere, but the only one I see with a yellow mark by the device is the usb stick. Any ideas on what to check..
