Does anyone know where I might find a wiring diagram (schematic) for building my own Null USB 2.0 Cable? Never doing things the easy way, I?d like to make my cable for transferring my settings and files to a new computer. ?Yes,? I know there are easier ways of transferring files, but I?d like to give this method a shot if I can make my own cable.

BFilmFan,
Thanks for the URL. The bottom line is, ?forget it.? I see now that a USB PC to PC cable (USB NULL modem) requires a USB hub in the middle, either as a separate box, or an in-line cable. If you want to build your own USB hub, fine, but they are so cheap, why bother.

Hi Dotjock
The USB Bridge for PC to PC connection: Does this contain a separate USB controller circuitry or is it a cross linked (D+ to D-)cable with DC (VCC Voltage) separation? Does it sound logical ? I need to know the concept.
Thanks
