K, jpilot doesn't work and I don't know why, but pilot-xfer works if and only if I 1) press the hotsync button 2) check which USBTTY the palm pilot has connected to, 3) then start pilot-xfer.
If I start pilot-xfer and then press the hotsync button, it jumps to a different USBTTY?
Regardless, I now have the keyboard driver installed (on the wrong Lifedrive) and I can verify that it works.
