cannot use USB webcam inside VM

Description

I have spent countless hours over the past week trying to find a way to make this work. But it really is starting to look as if USB webcams don't work in VMs. I created a USB filter, and when the guest boots up I can initially see I have a /dev/video0 device. But as soon as I try to use it, I end up with many USB errors logged in the guest, in the VirtualBox machine log, and on the host. And the /dev/video0 device then disappears from the guest.

Can someone confirm whether USB webcams do or don't work in VMs? At least so I know if I've done something wrong with my VirtualBox setup, or whether this is a known limitation?
