All, Just to post my experiences using Samsung SCX-4600 on Ubuntu 10.04
1. Added the following to /etc/sane.d/xerox_mfp.conf # Samsung SCX-4600 usb 0x04e8 0x3433 2. Added to /lib/udev/rules.d/40-libsane.rules (with other Samsung devices) to get permissions correct. # Samsung SCX-4600 ATTRS{idVendor}=="04e8", ATTRS{idProduct}=="3433", ENV{libsane_matched}="yes" 3. Made sure sane-find-scanner found it and xsane scanned a picture a few times (all worked). So I would say this scanner is supported. Now just need to look into how much work to get the buttons to work... Tom
