I am using LinuxMint v8.0 and having difficulty in getting my Benq S2W 4300U Scanner to work on my system.
After installing u176v046.bin in .usr/share/sane/snapscan, and editing /etc/sane.d/snapscan.con to read: #------------------------------ General ----------------------------------- # Change to the fully qualified filename of your firmware file, if # firmware upload is needed by the scanner firmware /usr/share/sane/snapscan/u176v046.bin # If not automatically found you may manually specify a device name. # For USB scanners also specify bus=usb, e.g. /dev/usb/scanner0 bus=usb I get an error message: Failed to start scanner: Error during device I/O typing lsusb in a terminal gives me: zed at zed-desktop ~ $ lsusb Bus 001 Device 008: ID 03f0:2f17 Hewlett-Packard EWS 2605dn Bus 001 Device 005: ID 05e3:0702 Genesys Logic, Inc.
