Baseband Description and Troubleshooting

USB

Before proceeding with the USB faults troubleshooting portion of this guide, attach a
DKU-2 cable between the mobile terminal and the PC. The PC must recognize that a USB
device has been attached and load driver(s) for that device. The mobile terminal appears
in the Device Manager dialog box.
If the mobile terminal appears, the USB device detection protocol is functioning and
indicates this is not a hardware fault. No further troubleshooting is possible.
