Kernel log: /var/log/kern.log

It looks like the driver does not find a supported sensor and/or the 
sensor probe routine has some pointer problems.

Do you know which sensor your cam is using? You might find some 
information about the sensor in the Windoz driver (.inf, .reg files or 
in the Registry itself).

I am not familiar with the m560x driver. So, I am not a lot of help 
here, sorry.
