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, Henning
