yeah, that is what I was afraid of. I understand what you are going through, it is hard. 

MAybe someone did this on this forum, but I do not remember the details or if it was really a TabletPC setup like yours. (I think not).

Those problems is why I opted for a "hardware" solution.  By emulating a recent device, one could use the "good" drivers that are easy to install.

If you ever decide to go that route, do not forget to order the 1$ 3.3v regulator that goes with it.  This is the "normal" Teensy 2.0 board (NOT the Teensy2.0+++)

This was a serial board -- there is no such thing as a VID/PID (which is a USB concept).

As far as I know, within the "original" TabletPC, is a configured differently because it expects a serial device through an "internal" serial port. (Which may or may not be registered as a COMx port).  These are CPU I/O port mapped on an "I/O Port" address number that resemble 0x3F8 / 0x2F8.  As far as I know, the USB to COM port converters do not map through an I/O Port and that reminds the biggest challenge. 

Having said that, I still think someone made it to work (but I can't remember if this information is true or not).

Teensy 2.0 is quite easy to find with Google: http://www.pjrc.com/teensy/  The important part is "ATMEGA32U4".  Buy it without the header pins but with its 3.3v regulator companion.
