Yeah, the non-pvusb devices should be listed as "assignable" if they
are handled by a driver domain.

--host does?

TBH: driver domains seem to be a reason to not support the --host
option. So the options are --all or no special option. I'm still
fine with both.

BTW: Do Xen concepts allow to assign a USB-device via pvUSB from a
driver domain to Dom0?
