== Status
Proposed
== Context
Certain VMs will need access to specific USB devices, but with passthrough from
the host we can only pass through whole USB controllers, not individual devices.
== Decision
USB controllers will be passed through to a VM with authorization controls
inside the VMs to forward a specific USB device using USBIP.
== Consequences
We need to modify the upstream USBIP daemon to support authorization.
