a scsi scanner is not recognized as scanner by udev , so the right on its /dev/sg* remains 640 root:root , prohibiting users to scan without prior manual rights change , for usb-based scsi-scanners to group is changed to "scanner" fixing this problem Reproducible: Always Steps to Reproduce: 1. ll /dev/sg* 2. start xsane Actual Results: 1. the sg-device of scanner has rights 660 root:root 2. xsane does not find the scanner Expected Results: 2. xsane should find the scanner 1. the right on device should be something like 660 root:scanner

media-gfx/sane-backends version? udev version? Relevant part of syslog output?
an easy fix for this derived from the udev-code for scsi-cdroms is this: the ATTR-ids are from scsi-kernel-src as xsane states somewhere in its docu SCSI-scanner can announce themselfes as Scanner (6) or as Processor (3) my scanner uses processor so there is no futher need to check this --- /etc/udev/rules.d/50-udev.rules 2007-11-24 23:30:06.107872779 +0100 +++ /etc/udev/rules.d/50-udev.rules~ 2007-11-24 23:30:06.057871935 +0100 @@ -265,7 +265,6 @@ # sd: 0 TYPE_DISK, 7 TYPE_MOD, 14 TYPE_RBC # sr: 4 TYPE_WORM, 5 TYPE_ROM # st/osst: 1 TYPE_TAPE -# scanner: 3 Processor, 6 Scanner # Setting timeout for tape-devices to 900 seconds # if you need timeouts for other devices add a similar rule @@ -276,9 +275,6 @@ # assign cdrom-permission also to associated generic device KERNEL=="sg[0-9]*", ACTION=="add", ATTRS{type}=="4|5", GROUP="522" -# assign scanner-permission to associated generic device -KERNEL=="sg[0-9]*", ACTION=="add", ATTRS{type}=="3|6", GROUP="817" - # Load driver for scsi-device ACTION=="add", SUBSYSTEM=="scsi_device", RUN+="modprobe.sh sg" ACTION=="add", SUBSYSTEM=="scsi_device", ATTRS{type}=="0|7|14", \

(In reply to comment #4) > sys-fs/udev: > [ I] 104-r12 (0) Uh, upgrade your udev to 115-r1 at least.

Created attachment 137073 [details, diff] add the detectin-rule for scsi-scanners to 50-udev.rules this patch is rebuild with udev-115-r1 it adds the detecton of devices with Type 6 (Scanner) and Type 3 (Processor) as already done in this rules-file for cd-burners. Type 3 is also accepted as scanner-device by xsane and it is the type my scanner reports
somehow the output from syslog got lost; here it is : Dec 1 21:29:49 vilya kernel: scsi0 : sata_via Dec 1 21:29:49 vilya kernel: scsi1 : sata_via [...] Dec 1 21:29:49 vilya kernel: DC390: clustering now enabled by default.

Hi udev-guys, do you think it is your job (if not, why?) or should this be handled by sane-backends somehow?
Should be OK for sane-backends-1.0.19, please test.
works for me with scsi-scanner (ID=3) sys-fs/udev-115-r1 media-gfx/sane-backends-1.0.19 media-gfx/xsane-0.995
