This actually is the best way to go about it as it is both faster and more secure than a usb proxy that passes via dom0. USB controllers short of a very poorly designed one that I don't know about lack any onboard firmware so as long as it is truly separate from your other "Trusted" controllers[1] and has FLR you are good to go. [1] Intel laptops have shared resources for their usb controllers so they aren't really separate. -- You received this message because you are subscribed to the Google Groups "qubes-users" group.

Might be fixed in 4.0 or a future version, but as a temporary workaround for problem USB devices like that you can assign an entire USB controller to your webcam-VM. It's not as nice because you lose isolation for that controller but it should work. If you want to try it, unplug all unnecessary USB devices. Shutdown both webcam-VM and sys-usb.

Which Qubes version are you using? What's the device you are trying to use? Can you provde more information? This is an error that has been reported before and there's an open ticket on qubes issues.
