Hmm, let me dig out one of my dongles first and see if it is broken too... If not I might be interested in getting yours but no promises - time is tight ;( Thanks. -- Dmitry -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo(a)vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/

It no longer works with older stuff either. So.. unfortunate timing of a hardware failure with kernel upgrade. Nothing to see here.
