USB Trouble Shooting
The Base Station's light flashes in Red cycles when the USB cable is
connected.
The Base Station cannot enumerate. The driver is probably not
installed correctly.
Occasionally the user will be unaware that he aborted his driver
installation. Once the process has started, it should finish
successfully. If it doesn’t, you will not see any data on the screen
when scanning.
