You may run into a problem here...  IIRC, the Palm USB cable is just 
that, a cable.  The Pal Pilot itself does all of the protocol 
translation, similar to my Kodak Digital Camera which had a DIN-8 
plug on the camera itself, and the a choice of a USB cable or a 9-pin 
Serial cable to transfer images to your computer.  The Camera 
actually has both interfaces built into it, and merely senses which 
type of cable is attached to it.

Also, IIRC, your standard Serial and USB do not use the same types of 
data transmission (I.e. Tx, Rx, RTS, DTR pins going high/low to 
represent data...) Which is why devices like the Keyspan USB-Serial 
adaptor are still rather bulky.

(And while I'm posting, how soon till you'll be able to 
reverse-engineer the Airport Extreme card ;)  Anything I could do to 
help out with that...)
