From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.0.1) Gecko/20021003 Description of problem: When running xsane as a mortal user it gives an error: "Failed to open device 'sm3600:1/3': Error during device I/O.". Running as root (and ignoring xsane's warnings about the dangers of doing so) solves the problem. Scanner is a USB Microtek ScanMaker 3600, FWIW. Version-Release number of selected component (if applicable): xsane-0.84-8 How reproducible: Always Steps to Reproduce: 1. Log in as a normal user and start X 2. Start xsane 3. Accept license agreement Actual Results: Error message cited above appears in a pop-up. Expected Results: Xsane main window should appear. Additional info:
If you make a symlink /dev/scanner pointing to the right device, this should work fine. It would be nice if kudzu did this for you I guess.
I had to add a script that changed the permissions of the device. I create a file called /etc/hotplug/usb/sm3600 containing: #!/bin/bash cd /etc/hotplug . hotplug.functions mesg setting permissions of $DEVICE chmod a+rw $DEVICE Then make this file executable (`chmod a+rx /etc/hotplug/usb/sm3600`). This works for me, but the /dev/scanner symlink doesn't seem to work.
Annoying thing. Add me to cc
Some of this was handled by USB hotplug scripts in later releases. For the Fedora Core development stream, handling of this is done/needs to be done via udev rules. Closing as WONTFIX for kudzu, as this is handled elsewhere in current releases.
