Yes, but not because of PVUSB support in xl.

According to that wiki, only dom0 backend is currently supported. And
our previous experience with PVUSB kernel drivers reveals it's really
unstable. Alternative they propose is to use backend in qemu process in
dom0, which is security disaster.

On the other hand, it turned out USBIP to be greatly improved over the
time and is quite useable. And it is possible to use it over any socket,
not only network, so we've connected it using Qubes RPC[2]. It will be
available in upcoming Qubes 3.2. There will be a separate announcement
about this major feature.
