[qubes-users] camera not connected after sys-usb switch

Hi!

I've switched my sys-usb to a minimal template and a dvm setup (according to this manual: https://www.qubes-os.org/doc/disposablevm-customization/). Everything works fine except the built-in camera. The camera is being detected during sys-usb-dvm startup, but when I try to connect it to another AppVM, I receive the message "Attaching device MyDevice to AppVm failed. Error: QubesException - Device attach failed: No device info received, connection failed, check backend side for details."

Am I missing some packages in the minimal template which are not listed here: https://www.qubes-os.org/doc/templates/minimal/#distro-specific-notes?

Best, P
