Hi Sorry for the late response. I only get the digest and don't follow all the topics. See below.

This is what another user, Einar > Jón, replied to you some days ago: > https://lists.freedesktop.org/archives/modemmanager-devel/2017-April/004409.html Note that qmi wwan is a kernel module, and it does not create a device in /dev. It does however depend on the cdc_wdm module, and that one should be seen in /dev. It should be loaded on startup, so you see it in dmesg. If all is well, you should have a /dev/cdc-wdm0 (and /dev/ttyUSB0 to /dev/ttyUSB3). Furthermore,the command lsmod should show you qmi_wwan, cdc_wdm and some related kernel modules. On my ArmXL: $ dmesg | grep -i qmi [ 4.371036] qmi_wwan 1-1.3:1.4: cdc-wdm0: USB WDM device [ 4.372191] qmi_wwan 1-1.3:1.4 wwan0: register 'qmi_wwan' at usb-musb-hdrc.0.auto-1.3, WWAN/QMI device, de:66:89:95:aa:b0 [ 4.373520] usbcore: registered new interface driver qmi_wwan $ lsmod | grep wwan qmi_wwan 11700 0 cdc_wdm 10185 2 qmi_wwan usbnet 21957 1 qmi_wwan $ ls /dev/*USB* /dev/cdc* /dev/cdc-wdm0 /dev/ttyUSB0 /dev/ttyUSB1 /dev/ttyUSB2 /dev/ttyUSB3 hope this helps Einar Jón _______________________________________________ ModemManager-devel mailing list ModemManager-devel@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/modemmanager-devel
