Very cool, thanks for working on this. I've done a quick review, mostly
from the usbredir pov rather then a code pov, and there is one thing
missing.

Now that virt-manager will have a usb-device selection dialog, it
should probably also enable usb autoredirection by setting the
auto-connect property of the UsbDeviceManager to true, this will enable
the "If the virt-viewer window has the current focus and I insert a USB
device, it will be automatically redirected to the guest" behavior
Leonardo is talking about.

I see that Cole is not necessarily a fan of it. Cole, you should give
this a try, most users love it. In virt-viewer we just always enable
it without any complaints. Alternatively it could be made an option
but I would default it to true.


I tried it several times, for virt-viewer, auto-usbredir property is set to TRUE by default, so
it supports auto-rediret by default. it works well for a single guest.
When there are multiple virt-viewer instance opened for multiple guests, the auto usbredirection becomes a little confusing, sometimes it is redirected to guest A, sometimes it goes to guest B
between I re-plugin the usb devices.

It is a really good feature. for virt-manager, multiple viewers more often stay opened for guests than virt-viewer, so it possibly cause some confusion for user. So I think using *disable* to this feature by default probably is better. we can give an option to enable it somehow.
