Hi,
Quick follow up on this…
The problem turned out to be this line in /etc/rc.local:
chmod a+rw /dev/video*
It wasn't being run, even though the other lines in that file were. So if I run that command manually after a reboot, the camera works fine.
Nothing to do with RHEL6 kernel version number (I tried RHEL6.4 and RHEL6.5), or the fact that the server had a RAID card in it.
Cheers,
Matt

However, we're finding that the SDK3 doesn't work on 64-bit RHEL6 (Kernel 2.6.32). I've not had the chance to test the EPICS support yet, as this is purely an Andor issue - their example programs fail to run correctly.
