See this for details, very similar case: usb wifi dongle + usb digital tuner. https://bugs.launchpad.net/ubuntu/+source/linux/+bug/256492 My problem also described in that bug report, got all the hardware and 100% reproducible situation, would be nice if somebody helps to debug it. -- To unsubscribe from this list: send the line "unsubscribe linux-media" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
