2.6.27-13 hasn't fixed it either.

It does work with 2.6.26.7 and the qc-usb-messenger driver 1.8 (qcmessenger.ko).
However, that drivers can't be used in 2.6.27, plus the 2.6.27 kernel claims to 
support the webcam.

I've fetched and compiled:

Added some of my own debug statements (USER_OPT=-DDEBUG barfed up
compile errors)

It seems to fail in usb_control_msg() for request 0x04, type 0x40, value 1059, 
index 0.
I'm kinda stranded there cause I haven't got the foggiest idea what that means 
and how to check if the webcam possibly doesn't understand that request nor 
what request should be sent instead.

I hope this extra info helps someone in tracking down the problem.
