E3372s working flawlessly on Dovado hardware

[Wezzo]

Hi!
Recently bought a compatible hardware I put 2.4.4-p3 pfSense on, and wanted to get the E3372s stick working with it so I could use my Dovado Pro router elsewhere. The E3372s modem is working flawlessly with the Dovado Pro router.
The stick is on 22.x firmware but I have a faint memory I switched from HiLink to stick mode using this method: "http://192.168.8.1/html/switchProjectMode.html", years ago when I bought the stick.

The Dovado router reports the same IP as speedtest.net so I'm definitely not behind any HiLink NAT, and have successfully opened ports in the past. I get speeds up to 150Mbit/s while the stick is plugged into the Dovado router.

How can the Dovado router achieve this? I've read that in serial mode PPP you can only get up to 21Mbit/s or something. Is the router using RNDIS?

With pfSense I tried to get the PPP working but the only link interface which is available is /dev/cuau0
I even added a delay to /boot/loader.conf
loader_delay="240"
Which didn't help.

usbconfig finds the modem on ugen0.2

Do you think I'll get this it working using the RNDIS mode? It doesn't seem all that easy.

Any advice?

Probably by using MBIM mode which FreeBSD, and hence pfSense, does not support.

If you're lucky you might just be able to choose a different config index to use. Try running:
usbconfig -d ugen0.2 dump_all_config_desc

If you want to use RNDIS mode you will need to import the urdnis kernel module from FreeBSD.
