Hi guys, I have the same problem with this xHCI controller. However my setup is a little bit different - I have a USB 2.0 hub attached to the root port, then a mouse attached to the USB 2.0 hub port. The hub is a MTT hub with 7 ports (other hubs have the same problem, so I don't think it is the hub problem). With some debugging I found it is "Secondary Bandwidth Error". When I insert the mouse directly into the root port of the Etron xHCI, it works without problem. However, when I use the same setup, but runs under Windows 8 preview edition, the mouse works normally, so I don't think this is hardware problem (but maybe it is a quirk hardware specifics that workarounded by Windows 8, Linux just has no luck yet). Anyone could look into this further? Maybe someone from Etron could tell us why?
