I have a similar situation.
My computer at work will no longer recognize the TP as you're describing but it still works on my laptop and other computers. My work computer wont do active sync mode or storage mode (for transferring files to SD). I have spent many work hours trying to resolve this issue with no luck.

To be clear: my TP works on any computer except for the one in my office. IDK what I did to piss it off.
