Unlikely. The interrupt routing is hard wired into the SoC and probably not messed up (unless the USB node in the device tree has been changed). You may have a problem with port_config (setup for single ended vs differential signaling) or some other electrical difference from the 5200. Beyond that it's not something that is easy to figure out over email. g. -- Grant Likely, B.Sc., P.Eng. Secret Lab Technologies Ltd.
