This will give you the /dev/pilot symlink which is very handy.  I

The following provides, and removes, the module automagically.
The key is to match the "add" udev action (?):


SUBSYSTEMS=="usb", ACTION=="add", \
    ATTRS{product}=="Palm Handheld*|Handspring Visor|palmOne Handheld",
\ RUN+="/sbin/modprobe visor"
SUBSYSTEMS=="usb", ACTION=="remove", \
    ATTRS{product}=="Palm Handheld*|Handspring Visor|palmOne Handheld",
\ RUN+="/sbin/modprobe -r visor"



Got all that useful info courtesy of the following web-page, and I used
it verbatim.

Bonus! the page talks about using Debian :-)

All of this would be a whole lot easier if there was some sort of trace
that tells you what udev is doing, verbosely.  udevadm monitor isn't
that useful.
