SANE_DEBUG=255
SANE_DEBUG_SANEI=255
SANE_DEBUG_DLL=255
and something forthe mustek (check the man page for it):
SANE_DEBUG_<backend_name_here>=255

The backend must detect the scanner if the Pid and Vid are correct, so
if you enable the debug symbols you can see where it goes wrong:
without debug it may not output that if "found" the scanner because
something goes wrong with the initialization perhaps?
