Right. This error -28 is given by the USB subsystem when there are many
devices on a same bus. If you raise the gspca debug level, you may see
that gspca switches to a lower alternate setting and that the webcam
is working (i.e. /dev/video0 should be created).

Then, as your webcam has never been tested with gspca v2, there may be
some remaining bug(s). Did you try my program svv? If it works, other
applications as mplayer (with v4l2:) or vlc (0.9.x) will also work.

Best regards.
