don't forget to add this patch also.

http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=502805

I was able to patch the qc-driver.c, but I had to replace the qc-usb.tar.bz2 file in the /usr/src directory because module-assistant kept wiping out the patched file.

the Line numbers weren't quite right. but the general idea atleast let me compile.
