Perhaps this bug should be reassigned to udev then, because it clearly did not do this for me. libsane should do this for you when it is installed so installation is more transparent.

Triggering a coldplug is not recommended AFAIK. I'm not sure what you mean by triggering a coldplug, sorry. Applying the rules on the system in its current state, outside of an hotplug event. The current policy regarding udev is to install the rules without triggering a coldplug event.

But after installing libsane, and before I restarted udev, unplugging the USB scanner and plugging it back in (which should trigger a hotplug event?) did not allow me to see the scanner as a non-root user in group saned. After I restarted udev, I could. Dave -- Dave Page [EMAIL PROTECTED] Jabber: [EMAIL PROTECTED] -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of unsubscribe. Trouble?

After I restarted udev, I could. The best thing would be to try to reproduce this and confirm it's a udev issue. Try commenting out the rule for your scanner, then restart udev, then uncomment it and plug your scanner. Check the permissions on the device node. If it doesn't work, rinse, repeat while running udevadm monitor. strace()ing udevd and touching a file under /etc/udev/rules.d shows udev reloading the rules just fine.

Bug#500837: libsane's udev rules not recognised
Package: libsane Version: 1.0.19-20 Severity: minor I installed libsane (as a dependency of kooka) and then connected my USB scanner (a Mustek 1248UB). The device nodes in /dev/usbdev* were owned by root:root and hence the scanner was not accessible by me - scanimage -L showed the scanner as root but not as the normal user. I had to manually restart udev to get it to read the rules file; after that (and unplugging and replugging the scanner) the permissions were correct and everything was fine. libsane should do this for you when it is installed so installation is more transparent. -- System Information: Debian Release: lenny/sid APT prefers testing APT policy: (500, 'testing') Architecture: amd64 (x86_64) Kernel: Linux 2.6.26-1-amd64 (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/bash Versions of packages libsane depends on: ii adduser 3.110 add and remove users and groups ii libavahi-client3 0.6.22-3Avahi client library ii libavahi-common3 0.6.22-3Avahi common library ii libc62.7-13 GNU C Library: Shared libraries ii libexif120.6.16-2.1 library to parse EXIF files ii libgphoto2-2 2.4.1-3 gphoto2 digital camera library ii libgphoto2-port0 2.4.1-3 gphoto2 digital camera port librar ii libieee1284-30.2.11-5cross-platform library for paralle ii libjpeg626b-14 The Independent JPEG Group's JPEG ii libsane-extras 1.0.19.10 API library for scanners -- extra ii libtiff4 3.8.2-11Tag Image File Format (TIFF) libra ii libusb-0.1-4 2:0.1.12-12 userspace USB programming library ii makedev 2.3.1-88creates device files in /dev ii udev 0.125-6 /dev/ and hotplug management daemo Versions of packages libsane recommends: ii avahi-daemon 0.6.22-3 Avahi mDNS/DNS-SD daemon ii sane-utils1.0.19-20 API library for scanners -- utilit Versions of packages libsane suggests: pn hplip none (no description available) pn hpoj none (no description available) -- no debconf information -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of unsubscribe.
