Hi,
I'm trying to get a 3Com Bluetooth PC card working on a Jornada 720
(hpcarm) device.
I tried the same thing a while ago, but got nowhere.  Also a Jornada
720, and also a 3Com Bluetooth card.  I think the problem I had was
something to do with loading firmware.  Or maybe it did get past the
firmware stage, and something didn't work later on.  I don't have the
Jornada or the card to hand at the moment, and this was quite a while
ago, so I can't remember.  Sorry, this really isn't a very helpful
response!
