When Debian Wheezy, testing version, is booting a strange message appears:

udevd[336] timeout usb_id--export /devices/pci0000:00/0000:00:1a.0/usb1/1-1/1-2.2/1-1.2:1.0 video4linux/ [502]

After this message, another message is displayed that loops for 120 secs:

udevd[337] killing /devices/pci0000:00/0000:00:1a.0/usb1/1-1/1-2.2/1-1.2:1.0 video4linux/ [502]

When it finishes looping, Debian starts normally and nothing seems to be "broken". I also killed the loop with Ctrl + C to break the loop and the system doesn't give any problem.

It seems that also there's an error on /sbin/modprobe -b blacklist

I posted the dmesg log after the comand

$ dmesg | grep uvc
[    9.016436] uvcvideo: Found UVC 1.00 device USB 2.0 UVC VGA WebCam (13d3:5710)

Does anyone know a possible answer? Is this a problem with camera driver??

EDIT:

in my /var/log/boot i have this message for udev:

startpar: service(s) returned failure: udev ... ^[[31mfailed!^[[39;49m
