Not sure why, but my Panda manages to get the VID:PID of the hub as well, while yours does not even get there. I may need a few more hours to debug this, unless someone beats me to it. ;) - Anand -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
