Yeah, but qcserial appears to select a different altsetting for the DM port for Gobi 1000, an altsetting which this particular device does not have. I didn't re-read the full thread I referred to earlier, but I think in it, Dan mentioned Gobi 1000 device requiring firmware to be loaded too. So if it's not a G1K device, we probably shouldn't be using qcserial even if the interface layout happens to match. Thanks, Johan
