What device and product ID is it showing now?

Did you try modprobing the usb serial driver using those values?

Same Dell custom IDs, as before. VID: 0x413C , PID: 81A8

Did you try modprobing the usb serial driver using those values?

Yes. I tried that several posts back. Remember, one of the modprobe commands gave me an error?
Later, I tried all 4 of the modprobe commands with sudo at the start.
With sudo, I didn't get errors, but it didn't help...same lack of functionality.

I just got a standard MC7355 card and it shows the desired VID: 0x1199. PID: 0x9041 IDs.

I'm going to give up on that horrible Dell Wireless card.
I don't need an impossible puzzle.

Right but the output you posted here showed the wrong vendor ID:

eric@ubuntu-vm:~$ /sbin/modprobe usbserial product=0x81a8 vendor=0x1199

You would need to modprobe against the current IDs to get a com port and then switch it.
If you tried that and it still didn't work I would probably be trying to do it Windows if you decide have another go at it. Otherwise the factory card should work far more easily.

@stephenw10,
So, are you saying the modprobe lines should be?

$ sudo /sbin/modprobe cdc_wdm product=0x81a8 vendor=0x413c
$ sudo /sbin/modprobe usbserial product=0x81a8 vendor=0x413c
$ sudo /sbin/modprobe qmi_wwan product=0x81a8 vendor=0x413c
$ sudo /sbin/modprobe qcserial product=0x81a8 vendor=0x413c

Yes exactly, you are telling the driver to attach to that specific device.

Hi Sir @stephenw10,

Sorry for bringing up this old post, May I ask if this modem/4G is supported by Netgate pfsense?

Actually, this is based on Netgate websites but I am afraid if the modems without h and s at the end will work in Netgate pfsense.

(https://docs.netgate.com/pfsense/en/latest/cellular/hardware.html)

The Huawei E8372 instead of Huawei E8372h without h at the end.

As well as,
The Huawei E3372 LTE USB-stick instead of Huawei E3372s LTE USB-stick without s at the end.

and

The Huawei E3372 LTE USB-stick instead of Huawei E3372h LTE USB-stick without h at the end.

Thank you!

I've not used any of those myself so I can't say. The best way is to just check other threads for existing reports of success.

Both a pretty old, but for installing and setting up a
LTE modem in pfSense it is even actual anymore.

As well as changing the USB IDs to something u3g will recognise you may also need to set the USB composition so it presents an AT port to pfSense.
