Re: [Qemu-discuss] EHCI usb passthrough not working with FreeBSD 8/9/10 guest

[Jon Doe]

Fedora 21 was on qemu 2.1.3 and Fedora 23 is on 2.4.1. I'm busy trying
to figure out how to use mock to build a previous version of qemu for
Fedora 23 but it's all a bit too complex for my packaging skill level
:-(
