About maximum speeds I am not yet sure, need to use this for a while. Is it possible that this device is some kind of abomination which can be used with pretty much every driver out there? Also, the vendor ID matches one already in the option driver, LONGCHEER_VENDOR_ID 0x1c9e, which covers quite a lot of smaller brand names. > > Does this device need modeswitching?

Nevermind, I found some drivers for it. It does indeed appear to be a Gobi-derived device, as you've found from the CodeAurora drivers. It should be driven by qcserial and qmi_wwan. Can you grab 'lsusb -v -d 1c9e:9801' after modeswitch for me? We need to find out what class of gobi it is. The rough mapping between codeaurora drivers and the upstream is: QCUSBNet = qmi_wwan QCSerial = qcserial Dan -- To unsubscribe from this list: send the line "unsubscribe linux-usb" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
