Description Markus Armbruster 2013-08-26 10:46:09 EDT
The Linux USB passthrough device has been rewritten upstream.  The old code is still around as device usb-host-linux, to simplify regression testing.  Upstream is expected to drop it in a release or two.

While we might want to keep usb-host-linux enabled for beta to help trouble-shooting any issues popping up, we definitely don't want it enabled in GA.

How reproducible:

Steps to Reproduce:
1. qemu-kvm -nodefaults -display none -monitor stdio -S -usb -device usb-host-linux

Actual results:
-device usb-host-linux is accepted

Expected results:
-device usb-host-linux is rejected, just like -device nonexistant
