adding the list back for future reference
Hi,
this is most probably a bug being tracked as
https://bugzilla.redhat.com/attachment.cgi?id=3D1260877 =
<https://bugzilla.redhat.com/attachment.cgi?id=3D1260877>;. The fix is
merged but not yet released.
A workaround could be re-adjusting of usb settings ofter VM creation
by a separate updating request.
Regards
Jakub

legacy is no longer supported in 4.0 (and not needed/useful since 3.6 =
already)
