MF823 LTE usb ethernet modem not appearing as ue0
bugbear last edited by
I am trying to get a MF823 usb dongle to work - it works OK in Windows and Linux, but I haven't succeeded with pfsense yet (which is where I really want it!) I notice that this device is reported to work, but I'm having trouble…
It seems that ue0 (or usb0) ethernet device nodes never appear (instead I'm seeing modem0 and umass0)
- I have applied AT command tweaks, so that mass storage is disabled. It appears as an RNDIS device
- The device works OK via a Knoppix boot CD, and on windows (on the same hardware), but not in pfsense.
I'm hoping someone can help with some ideas for what to try next?
- Are there some commands I can use to unload/reload kernel modules?
(On linux, I have found that if rndis_host and rndis_wifi kernel modules both are loaded, that unloading them and only loading rndis_host then creates the usb0 ethernet interface I'm needing)
+ I'm not so familiar with the bsd kernel, but it looks like umass0 is being loaded, and instead I want cdc to pick it up?
- Do I need a specific rndis kernel module? (From what I can see the cdce module probably supports rndis anyway)
PFsense can see the USB device, and seems to have created modem0 and umass0, and I need ue0 so that I can use it as an ethernet device

What should I try next?
Thanks in advance for any help!

Posting for future hackers….
I bought a 4G LTE modem from the official list. I chose the ZTE MF823 because it appears as an ethernet device.
Both nix and windows would see it as a network adapter and bring the connection up straight away. But not freebsd.
After several attempts at firmware tweaks and whatnot, i stumbled upon this russian thread: https://forum.pfsense.org/index.php?topic=76363.0
I don't speak russki, but i saw this command in the thread:
"usbconfig -u 0 -a 3 set_config 1"
so I started digging a bit.
My device appeared like this: ugen1.2: <zte,incorporated>at usbus1
And in the end, this command did the trick: usbconfig -d 1.2 set_config 2
The ue0 adapter appeared:
ue0: Ethernet address: 36:4b:50:b7:ef:44
ue0: <usb ethernet="">on cdce0
cdce0: <cdc ethernet="" control="" model="" ecm="">on usbus1
ugen1.2: <zte,incorporated>at usbus1
I could then set the wan interface as ue0 with dhcp, and the interface came up.
It's been stable ever since, even across reboots.
Unlimited 40/20Mbps for $20 a month... I like it.
