I read your post twice and still can't see your issue.
Some havr had problems with the device you noted, but most found it to work after hunting down updated drivers or just replacing it.
1. What's to say the unit works at all?
2. What device are you trying to talk to?
Some don't know to enable IR communications in the Palm units.
My computer doesn't have a serial port, to which I wanted to hook up a (serial) Tekram IrMate 210. I got hold of an adapter (Keyspan USA-19QW) but can't get them to play together. When I allocate the ports for the Tekram, should I be setting this to the same port as the Keyspan (so, in theory, it "passes through") or should these be allocated to different ports?
Thanks for any help!
