http://bugzilla.suse.com/show_bug.cgi?id=863991 Lin Ma changed: What |Removed |Added ---------------------------------------------------------------------------- Status|NEW |RESOLVED Resolution|--- |WONTFIX --- Comment #8 from Lin Ma --- If plugging a usb 3.0 device into a usb 3.0 port on host and passthru this device to a guest which doesn't have xhci controller, The device is invisible to guest, It's expected behavior because it's a speed mismatch. Changing usb controller to '3.0' in vm details page of virt-manager makes it work. But it exposed another issue: the usb device won't be re-attach to kernel once speed mismatch occured, I already sent this issue to upstream, will fix it according to feedback. -- You are receiving this mail because: You are on the CC list for the bug.
