Guten Tag,
sorry for the possible newbie questions, but I'm getting stuck.
My base problem is that I can access a USB device (Tektronix TDS 2014B oscilloscope) only as root. Initially "udevcontrol log_priority=err"'s output to /var/log/messages said that the device & endpoints were being added to group root with (IIRC) permissions 660. I tried a mod to 55-libsane.rules to add them to group usb (GID=1000) w/ permissions 664, but this seemed to have no effect. Copying the relevant lines to a new file, 10-libsane.rules (attached), causes /var/log/messages to say the device & endpoints are added to GID=1000 w/ permissions 664 (illustrated below), but this still does not allow non-root users to actually control the device. (I get an "Operation not permitted" error
if-and-only-if I lack root access.) The non-root user ("sarah") is confirmed as a member of group usb, which is confirmed as having GID 1000.
I don't seem to have udevadm on my system... although udevtest is available and displays the paths as you noted.
I'm running openSUSE 10.3 with linux kernel 2.6.22.18-0.2. SUSE
10.3's most recent official udev version is 114-19. I started to
install udev 126, but got several hundred conflict messages during
dependency-checking and got scared.
Any advice on trouble-shooting?
Thanks.
