So I gave up on IrDA, and instead am now trying to sync via the USB 
cradle that came with the Palm. The good news is that it attaches as 
ugen0 when I press the sync button on the cradle:

     ugen0: Palm, Inc. Palm Handheld, rev 1.00/1.00, addr 2

Things go south from there. Using pilot-xfer (from pilot-link version 
0.9.5 from ports), I press the Hotsync button on the cradle and then 
start pilot-xfer:

     [larse@hbo: ~] pilot-xfer -p /dev/ugen0 -l

        Unable to bind to port /dev/ugen0
        pi_bind: Invalid argument

So I tried coldsync (version 2.1.3, also build from ports), which seems 
to have some support for USB builtin:

     [larse@hbo: ~] coldsync -p /dev/ugen0 -t usb
     Please press the HotSync button.
     pconn_usb_open: Warning: Unexpected USB vendor ID 0x830.

I'm at loss on how to continue here. Any pointers?

Thanks,
Lars
