I recently put together a new system and am having problems with the usb ports. Windows seems to work okay until I plug anything into a usb port. When I do, windows recognizes the hardware and I use the cd which came with the hardware to install the device. After that time, one of two things happen. Either windows locks up or it gets stuck in a loop in which it loads, the desktop comes on and then it reboots. This happens over and over again. I have the wake jumpers on the motherboard disabled and I disable the wake feature on the Ethernet port. The other weird thing is that when I plug in my webcam into one of the ports, the light stays on all the time, whether the pc is on or not. The hardware worked fine before so I know its not that and the drivers all seem to be working okay and updated.
