Oops 2.4.25: USB visor module - Clie synchro

[Thom Borton <borton@phys.ethz.ch>]

Hello everybody

I occasionally run into a kernel Oops when I try to sync my sony clie, 
(PEG-SJ33) with kpilot. This is with a stock 2.4.25 kernel, but the same 
happened to me with the previous .24 and .23 kernels.

Strangely, it helps making a "pilot-xfer -l" the first time. This downloads a 
list of files on the clie (and never fails), and then kpilot will work as 
well.

As it is a kernel Oops, I thought this might be the best place to report, if 
it's a kde issue, tell me, I will ask there.

Best regards, John
