I believe Marius (CCed) has had some mixed results with that device. There are parts of the QMI <-> firmware interaction we don't understand, and this device could be one of those affected. Seems like quite a few devices will crash unless you send them the exact QMI commands they expect. I just found out that another ZTE device which I had previously given up as crashing, the MF60, works just fine if you send it a QMI_CTL 0x0020 (set instance id) command first. The MF820D was added to the qmi_wwan driver after a very brief verification of the QMI support. It is not well tested yet, and any success or failure is interesting. But I am not asking you to run and buy anything :-) Bjørn -- 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
