Subject: Problems using quickcam_messenger on ARM (FYI)

Hello Kernel-Developer,

Module quickcam_messenger seems to be broken (tried 2.6.18 and 2.6.22)
on 2 different NSLU2 (ARM). Picture is attached. Same kernel and module 
can be used without any problems on x86 here. I don't have any ARM 
device beside the NSLU2, so I cannot check.

The solution was to use Christian Magnusson's quickcam module. 
Everything worked without any problem. Webcam is:

Bus 003 Device 005: ID 046d:08f0 Logitech, Inc. QuickCam Messenger

Best regards and thanks for your work!

Markus

Kernel is:
Linux secure 2.6.18-5-ixp4xx #1 Thu Oct 11 20:42:54 UTC 2007 armv5tel
GNU/Linux
