Huawei ME936 modulo LTE Debian 10

Per uno dei miei notebook workstation, Schenker XMG P507, ho comprato un modulo LTE Huawei ME936, che per farlo funzionare, su Debian 10, c’è bisogno di qualche trick. Dopo aver creato una connessione Mobile Broadband, tramite Network-Manager, non si riesce a navigare, e come si può vedere sotto con i due comandi, la scheda viene riconosciuta:

$ lsusb
$ usb-devices

output:

La soluzione è quella di creare un file “udev-rule”, dove inserire in maniera specifica i parametri necessari:

$ sudo nano /etc/udev/rules.d/71-huawei-me936conf.rules

ed incollare dentro:

ACTION=="add|change", SUBSYSTEM=="usb", \
ENV{DEVTYPE}=="usb_device", \
ATTR{idVendor}=="12d1", ATTR{idProduct}=="15bb", \
ATTR{bNumConfigurations}=="3",
ATTR{bConfigurationValue}!="3" \
ATTR{bConfigurationValue}="3"

dopo aver riavviato, si potrà utilizzare la connessione LTE.
