usbredir support

[anonymix007]

usbredir is yet another protocol for USB device redirection.
It has some advantages over USB/IP, i.e. official cross-platform server. And in general, the protocol seems to fix some of the well-known USB/IP issues.

At some point there was even a somewhat working Linux driver submitted upstream, but was it rejected and no one worked on that since.

It would be great to have usbredir support here.

I don't think it should be implemented. It seems everything is implemented in userspace. This means poor performance and big latency. The popularity of this solution is also a big question. The more important is to add USBip server implementation as KMDF driver. I know how to do that, but it requires a lot of time.

It would be great if this is going to be implemented one day.
usbredir is quite popular. It's the go-to solution for USB device passthrough into a QEMU VM and is used in i.e. kubernetes and SPICE.
As for the performance or latency, it's hard to say anything without tests.
