From a9be4e7c48c4892c836bda1be4d550bb1a6732bd Mon Sep 17 00:00:00 2001 From: Gerd Hoffmann Date: Fri, 23 Oct 2015 14:27:10 +0200 Subject: usb-host: fix usb3ep0quirk test usb->speed is the usb speed the device is actually running on in the qemu emulation (i.e. from the guests point of view). So when plugging usb3 devices into ehci hostadapter this is HIGH not SUPER. To figure whenever the host talks to the device with superspeed we have to check speedmask instead and see whenever the superspeed bit is set there.
