I almost got my backend working today with Mac OS X. The most
important step was a fix to sanei_usb.c (the diff is attached
to this email). I am not that familiar with USB in general
or libusb to determine if this is safe for all platforms.=20
all I know is it works on Linux as well.=20

After corecting one byteorder problem in my backend, I was
actually able to initialize the backend, report all the=20
options to XSane (including the dynamic stuff frm the
scanner) and to start a scan. I then got all the data
for a low resolution scan, but the acknowledge message
that the backend sends to the scanner never made it out -
the bulk write command just hangs.=20
