Here are a couple of suggestions:
1. Make sure you post to the list, not just to Mitch--he is no longer at HP.
2. Since getting PC's to recognize different hardware is highly non-trivial
(i.e., I haven't a clue how to do it...spoiled by being a Mac user for so many
years, I guess), maybe what you ought to try is to work around the problem by
moving your mouse to a different COM port. I have no idea what algorithm HPComm
uses to decide which COM ports are available, but if the very first one is free
then perhaps it will happily use it.
