I'm not sure. I don't have any experience with libusb. The main reason
to not use it when I started the Mustek USB backend was the absence of
any documentation. Someone also mentioned that it's not possible to
restrict access to the scanner by setting permissions. I don't konw
about portability: in prociple, this library should be able to run on
everything that supports USB but I don't know what it really supports.
sanei_usb currently is tested (and works) with Linux and FreeBSD.

My opinion is: It's just one more library that may make life harder
when compiling/linking. If you include support into the umax backend,
be sure to make it compiling and running (the SCSI part) even if the
lib isn't present.

Concerning autodetection: This is also possible with sanei_usb and
newer Linux kernels.

Bye,
