One of the USB ports on our Parlor board is not functioning. Upon booting the kernel, it displays that it finds a USB 1.1 Hub (3 ports) and a USB 2.0 Hub (3 ports). When plugging a USB camera into the ports, one of them allows the OS to interface with the camera, while the other does not.

Using a multimeter, I found that the working port has +5 V at the + terminal in the USB port, while the + terminal in the other USB port appears to be floating, as it hovers around +5 mV.

What can be done to resolve this problem?
