Here is PoC based on qubesadmin API which can auto attach USB devices to any VM as required. By default Qubes auto attaches any device to the sys-usb VM, that helps with bad/malware full USB devices. But, in special cases, we may want to select special devices to be auto attached to certain VMs. In this PoC example, we are attaching any USB storage device, but, we can add some checks to mark only selected devices (by adding more checks), or we can mark few vms where no device can be attached.

I would love to see what all magical ideas you all come up with. Have fun with the code.

Btw, you can execute it in dom0 by

python3 autoattach.py
