Hi, Sorry about the longish reply, but I've just been through this with trying to get my film scanner working as a normal user. Strangely my Epson 1640SU works fine configured using YaST, and survives the reboot. On Sunday 09 May 2004 12:53, Keith Powell wrote: <snip>
However, the main problem I have found is that I can't get my Epson 1240U scanner to work. SUSE 9.0 found it and it worked perfectly.
The scanner kernel module is no more -- I've been having a few fun and games getting my head around how things are done in 9.1, kernel 2.6...
If I run xsane or xscanimage, they can't find the scanner. So I have set it up with YAST (installation didn't find it!). If I run xsane as a user, it still can't find the scanner. However, using a terminal and ignoring all the error messages, if I run xsane as ROOT, it runs and scans. After that, I can run it as a user until I shut down the computer. When I start the computer again, I have to run xsane as ROOT again before I can run it as a user. Very frustrating!
This is most likely a permissions problem in the /sys/bus/usb virtual filesystem managed by hotplugging - permissions aren't set when the scanner is detected by hotplug. Root only has read/write access to the 'file' that's created there. There's some info about how this works at: http://www.freecolormanagement.com/sane/libusb.html
I have re-installed 9.1 three times, and each time I get the same problems. I then did a clean installation of 9.0. Everything (including the scanner) worked. But after an upgrade, the scanner had disappeared again and I was back to manually installing it and running ROOT first.
I have a Minolta film scanner that's supported by Vuescan, and had this problem with it not being accessible to ordinary user. To solve this I put a variant of what was discussed in the link above in /etc/hotplug/usb ... a file I called minolta-ds5400.usermap with the following line in it: minolta-ds5400 0x0003 0x0686 0x400e 0x0000 0x0000 0x00 0x00 0x00 0x00 0x00 0x00 0x0 (ignore wrapping). The third and fourth entry: 0x0686 0x400e are the manufacturer and model codes obtained by running sane-find-scanner as root. The first entry minolta-ds5400 is the name of the config script to call -- this script is also placed in /etc/hotplug/usb/ -- make sure it's chmodded executable: #!/bin/bash if [ "${ACTION}" = "add" ] && [ -f "${DEVICE}" ] then chown root.users "${DEVICE}" chmod 660 "${DEVICE}" fi This works for me -- when the scanner is switched on or plugged in the script runs, setting permissions so all users can access the scanner.
I have checked and re-checked permissions in xsane, sane.d and the epson config file in sane.d. They are all OK.
It is counterintuitive, but it's done using the hotplugging system. There is a file called sane-hardcoded.usermap in /etc/hotplug/usb which I think is a list of all the scanners supported by Sane -- and calls a script called desktopdev which does the necessary voodoo to set permissions -- but I couldn't get it to work with the Minolta, by adding the usermap codes to this file. I think it may link somehow with YaST which doesn't recognise my Minolta as a scanner!
I'm lost! Has anyone else come across this problem, please?
Hope this helps! Now I can scan with both scanners using Vuescan, or with the 1640 using xsane. Jason
