integrated webcam stop working after starting virtualbox XP

[Zahar]

Please help
I have lenovo laptop with integrated webcam OS - Windows Vista. I installed VirtualBox-4.2.16-86992 with Windows XP.
After starting virtualbox and using webcam on the host ( vista) machine - the video is upside down and all pink / green.
Stopping virtualbox application doesn't help. The video is back to normal only after restarting the host machine.
I don't need the webcam on the guest machine and it is not installed on the guest machine.
I just want to be able to keep virtualbox running and have normal video on the host machine.

Thank you !

Make sure you don't have any blank USB filters enabled in the VM settings. If you need a filter, fill in enough fields to match only the device it needs to match.

well I even disabled (unchecked) "Enable USB Controller" in VM settings and it didn't help.
