HP hs3110 WWAN adapter not recognized

[Michael von Glasow]

The HP hs3110 WWAN adapter is not recognized and does not work out of the box.

The device is a rebranded Huawei MU736 but reports a different VID/PID pair (03f0:521d). With a few manual steps the device will work.

Add the following two udev rules:

# HP hs3110 (Huawei MU736)
ATTR{idVendor}=="03f0", ATTR{idProduct}=="521d", RUN+="usb_modeswitch '%b/%k'"
ATTR{idVendor}=="03f0", ATTR{idProduct}=="521d", RUN+="/bin/bash -c 'modprobe option && echo 03f0 521d > /sys/bus/usb-serial/drivers/option1/new_id'"

After that, a PIN prompt appears on boot, the device appears in Network Manager and can be configured. Before a conection can be established, the following AT commands need to be sent to /dev/ttyUSB2:

ATZ
ATQ0 V1 E1 S0=0 &C1 &D2 +FCLASS=0
AT+CGDCONT=1,"IP"

(I’ve successfully automated this using wvdial and running it once manually before establishing a 3G connection.)

After that, a 3G connection can be established.

Would be great if this were supported out of the box, especially if sending the AT commands could be automated.

PS: Debian apparently added the udev rules in usb-modeswitch-data, version 20160803-1; see https://launchpad.net/debian/+source/usb-modeswitch-data/+changelog.
