On my system this is fine. These rules are for FireWire cameras, not USB cameras. Furthermore, these rules are immaterial to kernels later than 2.6.36 (and also to some older kernels depending on kernel configuration). For current kernels, stock udev contains the necessary rules to make FireWire IIDC cameras accessible to users in the "video" group, as well as at least some boilerplate for distributions which prefer to do these things via ACL rather than Unix file permissions. Alas I can't answer Aryeh's question regarding USB camera access permissions. -- Stefan Richter -=====-===-= -=== -=-== http://arcgraph.de/sr/ |
