I upgraded to a n 8800 from a 7290, which connected easily to my PC both through the USB cable and through Bluetooth. The 8800 does neither no matter what I try.

What does happen, is that as soon as I connect the BB to the PC, I am treated to a symphony of Windows sound bytes, the type you here when you attach a device to the PC, then the one you would hear when you detach it the device. Attach, detach, over and over again in rapid succession.

When I attach the 7290, no problems at all, so the fault isn't likely the cable of the USB port.

What to do?
