Hi Greg,
the output is below, I also added a couple of debug-lines in the visor_open() function. Seems to me like port->read_urb is null and maybe that shouldn't be? Anyways, if I got that all wrong, don't hit me ;-). I would have like to look a little more around, but I have not really any idea of kernel programming so I have no clue who calls visor_open() Let me know if I can do anything else. Oh, and by the way, the crash happens, when I press "Sync" in jpilot, before that everything is fine.
see you later Stephan
P.S. sorry i took so long, but i was a little busy here ;-)
