Great! Thanks. If you have the qmi_wwan driver (and a recent kernel - don't remember exactly how recent...), then should be able to temporarily test this device by doing modprobe qmi_wwan echo "03f0 521d" > /sys/bus/usb/drivers/qmi_wwan/new_id If that works as I expect then the driver will bind to the suspected ECM interface. Things are least complicated if you already have the usb-serial driver bound to the other ports. The driver should log something to the kernel log (use e.g. dmesg to see this). The driver will hopefully create a wwan0 (or some other name) network device and a /dev/cdc-wdm0 character device. The latter can be used to test the embedded management protocol. If you have libqmi-glib then you should be able to test for QMI by doing something like qmicli -d /dev/cdc-wdm0 --device-open-version-info --wds-noop I actually do not expect that to work... But I do wonder if maybe AT commands will work? I don't think minicom wants to talk to a non-tty device, but you could try echo -e "ATI\r" > /dev/cdc-wdm0 cat /dev/cdc-wdm0 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
