Yes, the subsystem ID is different [1] (but Zotac program it the same as the vendor and device IDs here), however what you say suggests the problem is general to this Etron XHCI controller (1b6f:7023), as we'd suspect anyway.
Thus the more general patch I posted makes better sense perhaps?
Thanks, Daniel
