Thanks for your reply. Of course I've already tried that with no luck at all. The short story of things that already was tried (all of them failed): 1. Added scanner's usb id to xerox_mfp.conf. Double checked udev rules for correctness. Blacklisted usblp and built SANE with usb support. 2. Got reports that SCX-4200 "just works" with latest Ubuntu. Checked patches for Ubuntu package. None of them were related, however I gave it a try with no luck. 3. Installed latest Ubuntu just to be sure and eliminate the fact that I could forgot some small detail. 4. Tried several different versions of Samsung's Unified Driver on my Gentoo and that clean Ubuntu I've just installed. There are several comments related to this issue in Gentoo's bugzilla under the name "Coacher": https://bugs.gentoo.org/show_bug.cgi?id=139715 However, it is not SANE related. 5. Recompiled 3.0.8 kernel with changed Makefile to make it 2.6.40.8: VERSION = 2 PATCHLEVEL = 6 SUBLEVEL = 40 EXTRAVERSION = .8 I'll also make a try with 3.1 later but I don'y think I'll be lucky. I was trying to trick Samsung's driver so it is not SANE related too.
The syptoms I have are the same after all this tries: when I plug in my MFP I see dmesg info message, can see udevd output, even have my printer working smoothly, but scanner is dead. 2011/11/10 ABC <abc at telekom.ru> > Hello Ilya, > > Try to add USB ids of your device to your xerox.conf > and try scanimage -L > > -abc > > On Thu, Nov 10, 2011 at 10:44:54PM +0300, ???? ???????? wrote: > > Hello everyone. > > > > I am a long time Linux user and Samsung SCX-4100 owner.
