Ah, okay, so it is a three-step process: echo 0 to $path, then
SPICE redirection, then echo 1 $path....  if you want to do it
for several VMs for example, it should be very annoying.

I don't have such device to test but I wonder why that is needed
at all. What is the path you have to echo? Perhaps that can be
achievable in a different way with with libusb or some specific
driver's config that will get called when SPICE's redirection
takes place.

Hans, have you tried this kind of device before?

No, no API like that is exposed because for the set of devices
we redirect, it isn't needed. Let's see if we can workaround this
in the client OS first (e.g: configs) otherwise we can think
something in spice-gtk (probably QEMU too if you try to usb
pass through?)
