I don't have a howto but the sanei_usb API is pretty simple and explained here: http://sanei.meier-geinitz.de/sanei__usb_8h.html The assumptions are: - not more than one endpoint of each type: bulk-in, bulk-out, interrupt - interrupt endpoint access works only with libusb 1) sanei_usb_init 2a) call sanei_usb_attach_matching_devices with the "usb" lined from your config file or 2b) call sanei_usb_find_devices for any of the scanners you support 3) sanei_usb_open the device that was selected by the user 4) call sanei_usb_read_bulk, write_bulk or control_msg as you need 5) sanei_usb_close Bye, Henning
