Description of problem: I have an Epson Expression 800 SCSI scanner. It is detected with no problem as /dev/sg0 and gets user root, group lp and permissions -rw-rw---. So root can see the scanner, but regular users and network users can't see it. Changing the permissions to -rw-rw-rw by hand makes the scanner accessible to local users, but still not over the LAN. And of course, it won't be preserved across reboots. I added the network IP range to /etc/sane.d/saned.conf and added localhost to /etc/sane.d/net.conf, configured /etc/xinetd.d/sane-daemon as it was when it worked in F8, and opened port 6566 in the firewall. Any idea what I'm missing? Version-Release number of selected component (if applicable): sane-backends-1.0.19-10.fc9.i386 How reproducible: Always Steps to Reproduce: 1. See above 2. 3. Actual results: No network or regular user access to scanner Expected results: Network and regular users have scanner access Additional info:

Your scanner doesn't advertise itself as such, but as a "processor" device. I'll contact upstream about how we should work this.
OK FYI: $ sudo sane-find-scanner # sane-find-scanner will now attempt to detect your scanner. If the # result is different from what you expected, first make sure your # scanner is powered up and properly connected to your computer. found SCSI processor "EPSON Expression800 1.02" at /dev/scanner found SCSI processor "EPSON Expression800 1.02" at /dev/sg0 # Your SCSI scanner was detected. It may or may not be supported by SANE. Try # scanimage -L and read the backend's manpage. # No USB scanners found. If you expected something different, make sure that # you have loaded a kernel driver for your USB host controller and have setup # the USB system correctly. See man sane-usb for details. # Not checking for parallel port scanners. # Most Scanners connected to the parallel port or other proprietary ports # can't be detected by this program. $ sudo scanimage -L device `epson2:/dev/sg0' is a Epson Expression800 flatbed scanner device `epson:/dev/sg0' is a Epson Expression800 flatbed scanner After setting permissions to crw-rw-rw, I get the same results without sudo. No network access even if the firewall is down. And from dmesg: scsi 0:0:6:0: Processor EPSON Expression800 1.02 PQ: 0 ANSI: 2 target0:0:6: Beginning Domain Validation target0:0:6: Ending Domain Validation ... scsi 0:0:6:0: Attached scsi generic sg0 type 3 sd 1:0:0:0: Attached scsi generic sg1 type 0 scsi 2:0:4:0: Attached scsi generic sg2 type 1 sr 2:0:5:0: Attached scsi generic sg3 type 5
While we wait for upstream, is there any file that I can hand-edit to work around this issue? I'd like to be able to use the scanner in the meantime. Thanks.
This message is a reminder that Fedora 9 is nearing its end of life. Approximately 30 (thirty) days from now Fedora will stop maintaining and issuing updates for Fedora 9. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At that time this bug will be closed as WONTFIX if it remains open with a Fedora 'version' of '9'. Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, simply change the 'version' to a later Fedora version prior to Fedora 9's end of life. Bug Reporter: Thank you for reporting this issue and we are sorry that we may not be able to fix it before Fedora 9 is end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora please change the 'version' of this bug to the applicable version. If you are unable to change the version, please add a comment here and someone will do it for you. Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete. The process we are following is described here: http://fedoraproject.org/wiki/BugZappers/HouseKeeping
Sorry for taking so long. You can try to insert these lines into /usr/share/hal/fdi/policy/10osvendor/19-libsane.fdi (be sure to make a backup of it as this file is purposefully not marked as configuration and will be overwritten with each update): --- 8< ---------------------------------------------------------------------- <match key="@info.parent:info.subsystem" string="scsi"> <match key="@info.parent:scsi.vendor" string="EPSON"> <match key="@info.parent:scsi.model" string="Expression800"> <match key="info.category" string="scsi_generic"> <append key="info.capabilities" type="strlist">access_control</append> <merge key="access_control.file" type="copy_property">linux.device_file</merge> <merge key="access_control.type" type="string">scanner</merge> </match> </match> </match> </match> --- >8 ---------------------------------------------------------------------- Unfortunately I can't remember if I contacted upstream about it, if so nothing happened :-(. I'll try to remember doing that when I'm through with the post-F11 mass triaging.

I'll be upgrading to F11 soon, but in the meantime, is it possible to push a version to F10? Thanks.
My fault, I somehow changed the product version to 11 instead of 10... Anyway, I've buid F-10 packages at the same time, please check it out: https://admin.fedoraproject.org/updates/sane-backends-1.0.20-3.fc10
