The chipset in the Canon Lide 70 is not yet known, but it did not respond
positively to gl841 or gl646, so it is will not at present work with the 
genesys backend.  It has only 2 bulk endpoints, but no isosynchronous
endpoint, so it is different.  Some work is required to identify the chip, 
and the protocol.  Using usbsnoop on a small scan may provide helpful
information.  In any case, quite a bit of work lies between now and a 
successful sane scan.  I suggest obtaining a usbsnoop log and/or identifying
the chipset.  The recompile is not likely to work or provide useful
in my humble opinion.  Someone needs to initiage and carry that project
forward into development.

Good luck,
