BUG: Two USB cams on reporting to same Motion

System information:
Debian Squeeze 6.0.0
Kernel: 2.6.32-5-xen-amd64
Motion: 3.2.12
2x Logitech HD Webcam C270

I have two Logitech HD Webcam C270 and when I run one of them at a time motion works just fine, no errors and it records my video footages without problem, but in the same second I add both of them to motion it fails.

I have tried to run motion on one cam and Cheese on the other and that works, also when you flip the role, I have tried running both cams with Cheese at the same time and no problem, so its not the USB-controller, the two cams a plugged in to the motherboard on the same controller 00:13.2:2 and 00:13.2:4, I have also tried on two different controllers and one USB2- and one USB3-controller, so I can without a dough say that its not a hardware problem.

When cams running separately only change in conf-files is that one of the following lines in motionBoth.conf have bin removed:
