recentely i've update my cctv pc from fedora 8 to debian wheezy and all webcams stopped to works.
because i bought a lot of webcams and i've modified them for IR nightvision, now i must get them to work.
i tried searching on google, but with no results.
i appreciate any help.
because the system installation is new, eventually i can install an new version of fedora.
because low power processor and a lot of webcams (atom D525 with 8 webcams), i can't simply use mjpeg-streamer
the logs are:
