Created attachment 380121 [details] some command responses inquiring about the status of epson scanner which xsane cant seem to find anylonger Description of problem: this scanner used to work a month or so ago with various programs including xsane and worked pretty well. i thought i had a motor failure until i broke down and installed driver on a mswindows installation where the scanner works just fine including boottime micropositioner test (whir sound). tried scanner on machines with: kernel 2.6.30.9-102.fc11.x86_64 gnome 2.26 (see attachment for fc11 machine) kernel 2.6.31.6-166.fc12.x86_64 gnome 2.28 Version-Release number of selected component (if applicable): kernel 2.6.30.9-102.fc11.x86_64 sane-backends-1.0.20-4.fc11 (x86_64) sane-backends-devel-1.0.20-4.fc11 (x86_64) sane-backends-libs-1.0.20-4.fc11 (x86_64) sane-backends-libs-gphoto2-1.0.20-4.fc11 (x86_64) xsane-0.997-1.fc11 (x86_64) xsane-gimp-0.997-1.fc11 (x86_64) (at one point had installed iscan-2.23.0-3.ltdl7 (x86_64) <---from avayasys not fedora) (at one point had installed iscan-firmware-2.1.0-3.fc11 (noarch) ) [have similar results on fc12 machine] How reproducible: always Steps to Reproduce: 1. boot with scanner on or plug in after booted or turn on before or after boot 2. run xsane or another program that used to generate scan 3. get error message about no devices attached ( but seems to show up fine in attached logs ) Actual results: scanner worked fine a few updates ago but seems to have lost connection now. xsane gives: "no devices available" no micropositioner check at startup ( used to work ). same device works on mswindowsvista32 currently but just not in fedora. Expected results: micropositioner motors sound when boot machine or turn on scanner. xsane to see device. xsane to scan an image from seen device. Additional info: i gather there has been alot of kernel work related to drivers lately but am not sure whether to report this against kernel or sane or what. i expect kernel since power on startup test of micropositioner no longer seems to run and since saw a lot of kernel updates going through lately. if this should be reported against some other part then please suggest. did i forget to enable a service after some update? i have had several similar 'device not found errors' ( screen brightness control, gps receiver, now this scanner ) in the last few months while lsusb and such seem to see the devices and they used to work at some point. saw a note talking about now kernel architecture for drivers is mid-change but dont know how to differentiate among kernel, hal, backend, frontend sources.
Did this device ever work in Fedora 12?
No, i have never had it work with fc12, but i have only tried it recently when i found i had problems with fc11 so i am not sure that tells you as much as you might hope.
Created attachment 380853 [details] parts of dmesg, lsusb, lshal from fc12
I have the same problem with an Epson Perfection 3590 scanner on F12. It worked in earlier Fedora releases (F9 and F10, I think, but I probably didn't try it in F11). It appears to be a permissions problem, as xsane finds it just fine when run as root. The Epson 3590 scanner is listed in /lib/udev/rules.d/65-libsane.rules, and I verified that the idVendor and idProduct are correct. lsusb output excerpt: Bus 002 Device 007: ID 04b8:0122 Seiko Epson Corp. Perfection 3590 scanner
i dont know if i am just thick or if this is new but i just noticed that when i start xsane on fc11 the window title has the device name in it and that device is a webcam not the scanner. i ran the attached commands and it looks like the epson scanner is detected by sane-find-scanner but not by scanimage both for normal user and for root? so this means that the scanimage program has lost capability for epson? i dont see what in the configuration files would select the webcam over the epson as they are both listed in the various files but that kind of seems to be whats going on either by selection or by limitation. i will attach the scanimage and sane-find-scanner command results. the current kernel is kernel-2.6.30.10-105.2.4.fc11 (x86_64)
Created attachment 388588 [details] epson is there but sane wont scan from it anymore
on an fc12 system the scanimage and sane-find-scanner results were similar. fc12 system was running kernel 2.6.31.12-174.2.3.fc12 (x86_64) and sane-backends version 1.0.20 as well
device is successfully scanning now. went with closed driver plugin so scanner up for now with currently: kernel 2.6.32.10-90.fc12.x86_64 gnome 2.28.2 sane-backends-1.0.20-11.fc12 (x86_64) sane-backends-libs-1.0.20-11.fc12 (x86_64) xsane-0.997-3.fc12 (x86_64) xsane-common-0.997-3.fc12 (x86_64) xsane-gimp-0.997-3.fc12 (x86_64) grudginly installing (no offense avasys, much appreciated) www.avasys.jp: iscan-2.24.0-4.ltdl7 (x86_64) www.avasys.jp: iscan-plugin-gt-x770-2.1.1-2.c2 (x86_64) (see attached) 0) from what i read the closed plugin translates a nonstandard seiko/epson communication protocol that the sane-backend doesnt understand because its closed? : http://lists.alioth.debian.org/pipermail/sane-devel/2007-October/020047.html Olaf:"The Perfection V500 does not speak the protocol that the epson backend assumes. There is just about zero chance that it will work with any of the other backends that support EPSON devices (snapscan, plustek). If support for this scanner is added to the epkowa backend, then it will require a plugin which takes care of the protocol conversion. " 1) so that means that the system was initially working because i had the protocol conversion plugin installed maybe? the breakage was due to change in plugin install/update status maybe? so installing the closed plugin fixed the scanner? 2) while rechecking sane site for support status at http://www.sane-project.org/lists/sane-mfgs-cvs.html lists the epson perfection v500 ( aka GT-x770 aka usbID=0x04b8/0x0130 ) as 'unsupported go to www.avasys.jp for closed driver plugin (http://www.avasys.jp/lx-bin2/linux/scan/DL1.do)' so i temporarily give up and grudginly installed the closed plugin and now scanner is up again but this solution is not cool. 3) i dont know if i only had it working originally by virtue of the closed plugin or if something changed but that is where we are now... maybe there is more to the issue than i understand but not real happy about this from an open-ness standpoint. i dont have time to mess further with this now as i have a scan backlog to clear now that the scanner is up. however, guess i need to shop for a more open scanner when time allows.

Aw that sucks. Not much I or SANE upstream can do then I suppose unless Epson opens up specs...

If you were relying on the epkowa backend, it's been removed from libsane-extras a while ago already. You'll need to get it from the Avasys website directly.

It's been removed at the request of Avasys when they started providing Debian packages and I got fed up dealing with a number of issues with epkowa (most notably ABI changes for the binary plugins). > > The drivers available on Avasys website are all epkowa type? (On the > > "All-in-one" page of the Avasys website there is no PM-A820 driver. ) Yes, epkowa is Epson's backend for all their models. If your model is not listed, then it's not supported AFAICT.
