I recently tossed my DHP at a local buddy and he used the latest software with my Rat Shack cable and it worked 100% for him.

Was totally impressed by it. I know the Keyspan is the most widely accepted cable, the Rat Shack is in the "it should work" list.. overall it works very well for me. Yet I can't say if it's the cable or pure luck. With DHP it's probably more luck than hardware.
