Alcatel Onetouch 4G L850V LTE USB modem it is not visible in the PPP configuration

yanlb

I have Alcatel Onetouch 4G L850V and it's connected to the firewall. When trying to configure it as PPP in the links interfaces only appears /dev/cuau0 and /dev/cuau1:

Here is the device data:

/root: usbconfig
ugen1.1: <AMD EHCI root HUB> at usbus1, cfg=0 md=HOST spd=HIGH (480Mbps) pwr=SAVE (0mA)
ugen0.1: <0x1022 XHCI root HUB> at usbus0, cfg=0 md=HOST spd=SUPER (5.0Gbps) pwr=SAVE (0mA)
ugen1.2: <vendor 0x0438 product 0x7900> at usbus1, cfg=0 md=HOST spd=HIGH (480Mbps) pwr=SAVE (100mA)
ugen0.2: <Alcatel MobileBroadBand> at usbus0, cfg=255 md=HOST spd=HIGH (480Mbps) pwr=ON (500mA)

The PFsense recognizes it as ugen0.2

/root: usbconfig -d ugen0.2 dump_device_desc

I try to change the mode of the device but:

Any idea?

I buy this LTE modem because it is in the list of moden 3G / 4G compatible at https://www.netgate.com/docs/pfsense/cellular/known-working-3g-4g-modems.html

My idea is to use this device as a backup WAN line connection.

Thanks

What do you have in that config file?

Unfortunately a lot of manufacturers change the firmware or even hardware of devices without changing the model name.

That device is listed here as something different:
https://github.com/pfsense/FreeBSD-src/blob/293707af843ce1b4208eed3b8427b72356ea06f0/sys/dev/usb/usbdevs#L4415

You may be able to change it's mode permanently in another OS.

Hello Stephenw:

When I connect the dongle:

Sep 20 08:37:49	kernel		ugen0.2: <Alcatel MobileBroadBand> at usbus0
Sep 20 08:37:49	kernel		umass0 on uhub1

Sep 20 08:37:49	kernel		da0: quirks=0x2<NO_6_BYTE>

If you notice the system recognizes the dongle as if it were a usb memory
And...

cat fstab

/etc: camcontrol devlist

<ONETOUCH ESTORIL 2.31>            at scbus2 target 0 lun 0 (da0,pass1)

And the configuration files have not been touched and I am not config PPP.

Any suggestions?

You are using the configuration file /usr/local/share/usb_modeswitch/1bbb:f000 with usb_modeswitch though.
What's in that file?

Steve

@stephenw10
I use that command to try to change the way of working of the dongle since this file is the one according to the vendor and the product in question. That's the command to change mode of work which is described on https://www.netgate.com/docs/pfsense/cellular/known-working-3g-4g-modems.html#modems-reported-to-work-as-ethernet-devices, but for Alcatel L850v theoretically
.

Right I understand that. It looks like you need to switch the device to PID 0x0017.

But your command is referencing a config file here /usr/local/share/usb_modeswitch/1bbb:f000 what have you put in that file for usb_modeswitch to use? Or what is in it by default?

Steve

stephenw10

Or maybe pid 0x0195 for newer versions.

http://www.draisberghof.de/usb_modeswitch/bb/viewtopic.php?p=15496#p15496

Looks like that will give you an RNDIS device which you should be able to use with that kernel module loaded.

By default. And I tried (to test) with 1bbb:000f , 1bbb:00ca , 1bbb:011f , 1bbb:022c , 1bbb:025e , 1bbb:f000 , 1bbb:f017 , 1bbb:f052 and the same result.

Very interesting but it generates this error:

Yes, that's what I think. The system recognizes it as if it were another device, a USB memory.

stephenw10

That was the output of running at the command line without a referenced config file?

It looks like it's having a hard time reading the config value though I'm not sure why since usbconfig is reporting it. Potentially some Linuxism.

It has a uSD card slot so it should always appeat as a storage device in addition to whatever else it presents.

Steve

yanlb

No, that was the output of running with 1bbb:f000. I'm still trying to make it work but I have not succeeded
Thank you in advance for your help

stephenw10

Have you upgraded to 2.4.4 yet? Are you seeing the same error there?

I have modem Alcatel OneTouch l850v
idVendor=0x1bbb
idProduct=0x0195
PFSense version 2.4.4-RELEASE-p1

This modem work if load module if_urndis.ko. I copy this module from another FreeBsd installed system 11.2. This file is in /etc/boot/kernel/if_urndis.ko
After load module modem is ue0: network interface, and autoconnect to Internet.
You must disable PIN to sim card.
