From: Jan Kiszka <address@hidden>
This follows the logic of host-linux: If a 2.0 device has no ISO
endpoint and no interrupt endpoint with a packet size > 64, we can
attach it also to an 1.1 host controller. In case the redir server does
not report endpoint sizes, play safe and remove the 1.1 compatibility as
well.
