Re: Oops when syncing Sony Clie 760 with USB cradle

[Stephan Gutschke]

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 ;-)
