As in your experience, the only way the PocketPRO shows any life at all on the USB port is if the cable supplied with the PocketPro is used. The interesting thing is that when the PocketPRO is FORCED to downshift to USB1.1 speeds it works flawlessly. From that I am guessing that the problem is hardware related and not software related.
I have no problems with other USB2 devices in Windows. Unfortunately, all my (3) Windows machines have the same chip series and the same erratic problem.

It runs fine/fast under Ubuntu, any cable. Same hardware (connection), so the physical layer is working.
