I don't doubt that the explanation given for why it is doing this is accurate. It is feasible and technically sound.

However, the point of this was: The Touch Pro and the Diamond BOTH charge off of my POWERED USB HUB without having the computer on. My TP2 on the other hand won't charge unless it has the computer on.

I was hoping there was some registry setting, driver, or other tweak that could be done to force the HTC TP2 to charge via the USB Hub in a manner similar to the Diamond and original TP.

This was not a limitation in the other phones I've had. Both the Diamond and the TP could draw between 700-800 mA from my particular powered USB hub when only one device was plugged into it at a time.

It seems like HTC has become "bitchier" about what they will let the phone charge from and have lost some of the versatility in charging that I enjoyed with the other phones. I really like the TP2 a lot, but this is a small disappointment that I wish had a solution. If I run across anything that changes this behavior, I'll be sure to post it back here.
