Hello folks, my first post here so bear with me

Got this beast working on DD-WRT
Switches from 2020:2030 to 2020:2033 with standard eject. I haven't (yet) sniffed the message.
The stock linux driver installer is a big pile of youknowwhat.. installs the device as a dialup modem.
It's got a Qualcomm MDM 9225 chip and works nice with qmi_wwan

Hello folks, my first post here so bear with me

Got this beast working on DD-WRT
Switches from 2020:2030 to 2020:2033 with standard eject. I haven't (yet) sniffed the message.

Thanks for reporting this new device, I assume standard eject means that you have ejected the virtual cd-rom from cmdline.
You can try to get usb_modeswitch to send a standard eject message sequence by:
usb_modeswitch -v 2020 -p 2030 -K -W

The stock linux driver installer is a big pile of youknowwhat.. installs the device as a dialup modem.
It's got a Qualcomm MDM 9225 chip and works nice with qmi_wwan

That's what happens when neither the chip manufacturer (MediaTek) nor its customer (Telewell) cares about getting the dongle supported in linux.
LTE CAT4 device but will be limited to around 25Mbps when used with pppoe dialup...

The interface layout according to the generic MediaTek Win driver:

MI_00 Network Connect HS-USB Diagnostics
MI_01 Network Connect HS-USB Modem
MI_02 Network Connect HS-USB AT Port
MI_03 Network Connect HS-USB NMEA
MI_04 Network Connect HS-USB WWAN Adapter (that is qmi_wwan for linux)
MI_05 USB Mass Storage Device

Please paste the output for the dongle in ddwrt when issuing the cmd:
cat /proc/bus/usb/devices.

I already used the usb_modeswitch -v 2020 -p 2030 -K -W and it works.

I haven't yet managed to fully automate the process on dd-wrt (in asus n18u).
After modeswitch four devices (/dev/cdc-wdm0 to 3) are created but I have to manually
kick up the wwan3 if and run udhcpc command. (and had to change the wan settings in nvram to get it routing the net).

Attached windows log from dongle insert. Taken with USBPcap, can be read with Wireshark.
Let me know if you need more

Looks like the device is switching correctly (2020:2030 → 2020:2033), so usb_modeswitch is doing its job.

The issue is probably what happens after the switch — most likely driver binding. Check dmesg and see if it attaches to something like option, qmi_wwan, or cdc_*.

If it doesn’t bind properly, the modem won’t work even though the switch succeeded.
