The other threads are "Can't get any video" here: http://www.zoneminder.com/forums/viewtopic.php?t=12493 and "'mu -d <device_path> -q -v' error" http://www.zoneminder.com/forums/viewtopic.php?t=14049 .
Here are the things I'm seeing:
1) I run Zoneminder with a Panasonic network cam which works just fine. I've disabled that as I try to troubleshoot this Logitech.
2) The device works fine under xawtv.
3) cat /proc/sys/kernal/shmall shows 134217728 and shmmax also shows 134217728
4) /var/log/zm is empty. /var/lib/zm doesn't exist.
4) Running "zmu -d /dev/video -q -v" as a regular user, I get "Aborted." Running it as root, I get back "Error, failed to query crop /dev/video0/: Invalid argument." As root, if I add -V 2, I get the "query crop" error. If I change that to -V 1, I get "Error, failed to get channel 0 attributes: Invalid argument." None of these commands log anything to /var/log/dmesg.
In /var/log/syslog, however, I see this with the -V 2 flag:
Code: Select all

6) In the Zoneminder console, the source for the camera is red, and if I click on it, I get a missing image. Firefox is stuck on "waiting for localhost" forever.
Sorry for the long post. I'm just trying to give everyone as much info as possible. Any advice on how to fix this would be appreciated. Thanks!
