[sane-devel] MP730 driver broken since pixma-0.12.2

Apparently failing on first usb write attempt, so something wrong with libusb
or low level usb communication (this portion of code is common to all PIXMA
devices). 

Could you add all usb logs :

$ export SANE_DEBUG_SANEI_USB=255 
$ export SANE_DEBUG=255 
$ export SANE_DEBUG_PIXMA=21 
$ scanimage -T  2> /tmp/logfile

Zip and send back the /tmp/logfile
