The kref errors are due to the urb not being properly initialised. I've
added some calls to usb_init_urb and the new patch is at:
 
http://the.earth.li/~noodles/wcusb/wcusb-26-2.diff

Still hard crashes (not even magic SysRq works) shortly afterwards
though. I can run ztcfg ok, but haven't managed to get enough time
before the crash to run usbfxstest. Plus I don't see any output that
indicates what's going wrong.
