Been playing around with the PIC18F13K50 and 14K50 with PBP to utilise the UBS functionality via a "Low Pin Count Development Kit Board". After programming, I can connect the PIC & board up to my home XP desktop PC through USB and it works a treat. However, if I connect it up any other computer, I receive a "USB Device Not Recognized" message and suffice to say I have no USB access.

Any ideas as to what the problem could be?

Thanks for any help,

Troy
