Sorry for not checking earlier. I have just tried again after updating software and I can confirm that my scanner works properly again. Thanks.

My kernel is (uname -r) 3.16.0-4-amd64. I have a CanoScan LiDE 25 which apparently uses the plustek backend.I can confirm this scanner worked fine when the same computer was running debian wheezy. I appear to have the same, or at least similar, problem to that reported on this Ubuntu site:Bug #1250196 “sane plustek backend not working on USB 3 root hub...” : Bugs : sane-backends package : Ubuntu But my error seems independent of any USB3 ports. I have tried the same scanner on two separate computers both amd64 systems both freshly installed with debian jessie - one has usb3 ports and the other has only usb2 ports. Both produce the same errors and on both the scanner doesn't work. Please note that this scanner previously worked fine on my debian wheezy system (same computer) before I installed debian jessie. I have been using this scanner for some 4-5 years on various debian systems without much trouble. Now following installing debian jessie it doesn't work. The scanner is recognised with the sane-find-scanner command:# sane-find-scanner # sane-find-scanner will now attempt to detect your scanner.

Bug#774830: simple-scan: pixma 04A9173B 'Access to resource has been denied' over remote desktop
Hello Andreas, first thanks for your bugreport. I don't use x2go, but my first hint was: Are the x2go-server user in the group scanner?

Bug#774830: simple-scan: pixma 04A9173B 'Access to resource has been denied' over remote desktop
-BEGIN PGP SIGNED MESSAGE- Hash: SHA1 Package: simple-scan Version: 3.4.2-1 Severity: minor Dear Maintainer, simple-scan does not work over x2go-remote-desktop session. See there: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=761398 It is most probably a problem with user-rights and and with the sane-backend. When trying to scan, it looks like this on the terminal: andreas@md-ho:~$ simple-scan p11-kit: invalid config filename, will be ignored in the future: /etc/pkcs11/modules/gnome-keyring-module ** (simple-scan:23088): WARNING **: scanner.vala:801: Unable to get open device: Access to resource has been denied xsane says: 'Failed to open device 'pixma:04A9172B': Access to resource has been dnied. But scanning works, when there is a local session running on the machine (i.e. the remote-desktop server) from the same user. Normally this is no problem at all for thin-clients, because they do not have a scanner connected to the desktop-server. But in my case it is a problem. I also do acknowledge that not many people do have this problem, so it is severity 3 only. Please let me know, if I should rather report this against the sane-backend. I also report this to x2go. - -- System Information: Debian Release: 7.8 APT prefers stable-updates APT policy: (500, 'stable-updates'), (500, 'proposed-updates'), (500, 'stable') Architecture: amd64 (x86_64) Kernel: Linux 3.2.65cags (SMP w/2 CPU cores) Locale: LANG=en_GB.UTF-8, LC_CTYPE=en_GB.UTF-8 (charmap=UTF-8) Shell: /bin/sh linked to /bin/dash Versions of packages simple-scan depends on: ii dconf-gsettings-backend [gsettings-backend] 0.12.1-3 ii gnome-icon-theme 3.4.0-2 ii libc62.13-38+deb7u6 ii libcairo21.12.2-3 ii libcolord1 0.1.21-1 ii libgdk-pixbuf2.0-0 2.26.1-1 ii libglib2.0-0 2.33.12+really2.32.4-5 ii libgtk-3-0 3.4.2-7 ii libgudev-1.0-0 204-14~bpo70+1 ii libjpeg8 8d-1+deb7u1 ii libsane 1.0.22-7.4 ii xdg-utils1.1.0~rc1+git20111210-6+deb7u1 ii zlib1g 1:1.2.7.dfsg-13 simple-scan recommends no packages. simple-scan suggests no packages. - -- no debconf information -BEGIN PGP SIGNATURE- Version: GnuPG v2 iEYEARECAAYFAlSuNqsACgkQ5+rBHyUt5wv8wQCgwPoz1+9lw0p1Z08I7+V3oirf h8oAnRrtX8ncOYirI9/4OwM9fwhONjr7 =xaIE -END PGP SIGNATURE-
