Hi

The USB to Serial connection does not seem to be working on windows 8.1

I have the XBIB-U (Rev E) development kit (Board is Rev A)

When i insert the USB cable 99% of the time it USB device is not recognised. On one or two occasions I have managed to get one to work, but not reliably.

Have tied in different usb ports.

## The error in the device manager is:

Windows has stopped this device because it has reported problems. (Code 43)

## A request for the USB device descriptor failed.

I have installed new drivers, but no luck
