Hey, don't forget to keep the rest of us informed on what's going on! I've tried umpteen times to get USB stuff working on my Intermec/Telios with no success whatsoever.
Don't mean to be negative here but how exactly are you guys going to fit the Ratoc card AND cable into the Jornada's CF slot? Surely you'll need to go through the PCMCIA slot with an adapter? Won't that change the way the drivers will need to be written?
Good luck with this project, hope to see some results in the not too distant future!!
