Huawei E3372 USB Modem won't show up

[DjJoakim]

Hey!
First of all, i know there are a bunch of topics about the USB modems, i have read (not all) but alot of them, and i still can't get my modem to work as ethernet device.

My plan is to have the USB Modem to work as failover if my landline goes dead.
So, when pfsense boots up my usb modem shows as cd1, as you can see here in the logs

Oct 24 21:04:17 kernel cd1: <HUAWEI Mass Storage 2.3M> Removable CD-ROM SCSI-2 device

Then, when i try to do
usb_modeswitch -v 12d1 -p 1f01 -c /usr/local/share/usb_modeswitch/12d1:1f01

The logs tell me this

Oct 24 21:10:21 kernel ugen3.3: <HUAWEIMOBILE HUAWEIMOBILE> at usbus3 (disconnected)
Oct 24 21:10:21 kernel umass0: detached
Oct 24 21:10:21 kernel (cd1:umass-sim0:0:0:0): Periph destroyed
Oct 24 21:10:21 kernel cd1: <HUAWEI Mass Storage 2.3M> s/n 0123456789ABCDEF detached
Oct 24 21:10:21 kernel cd1 at umass-sim0 bus 0 scbus6 target 0 lun 0

and then i have to reboot pfsense to see the device as cd1 again, after the usb_modeswitch action nothing happends..

Desperate for some help, i am pretty new to this!

Thanks!

If it's not showing you a new ue(4) device after switching the mode it probably isn't available. It might require a USB quirk to set the config index.
Try running: usbconfig dump_all_desc before and after switching. See what ports it's presenting.

Okey, well i am a bit new to this, so i don't really know how to do that.
Yes, when i did usbconfig dump_all_desc before it showed me "Huawei etc etc.." as 3.2, but then when i did usb_modeswitch it went missing from that list..

[stephenw10]

Ok so it changed to a different device, which is expected, and seemingly one that is nit recognised. So what did it show after the modeswitch?

[DjJoakim]

@stephenw10 After i do that, the usbconfig dump_all_desc only shows me the same devices as before, but without ugen3.3, only 3.2, so it's gone from the list..
And the last i can see in the logs is that it's disconnected, after i did usb_modeswitch
Oct 24 21:10:21 kernel ugen3.3: <HUAWEIMOBILE HUAWEIMOBILE> at usbus3 (disconnected)

Hmm, I expect it to dissapear and then re-appear as a new device. Nothing much we can do if it never appears again. Maybe you're switching it to the wrong mode.

Does it have more than one config index when you first connect it?

@stephenw10 I use this command when i changed it, don't know if it's the right one:

usb_modeswitch -v 12d1 -p 1f01 -c /usr/local/share/usb_modeswitch/12d1:1f01

Hmm, i don't really know how to see that, i need to reboot pfsense to make it pop up again, i will do that and then see what it tells me.

[stephenw10]

The output of usbconfig dump_all_desc will show you that. If you post it here we can check it.

[DjJoakim]

@stephenw10 This is what i get without doing anything, since it flagged the code as spam, here is the code;

[stephenw10]

Mmm, only 1 config index in the default mode so nothing we can do there.

It really disappears completely after running modeswitch?

If so the only thing you can do there is run a different modeswitch command. Or trying to switch it some other way like just ejecting the virtual CD drive.
Some devices can be permanently switched from their web interfaces if you access that in some other OS first.

@stephenw10 Yep, all the other devices that are in that list are still there, but that one is just gone... and i don't really know where to find it..

I have now tried to change it trough another computer, but there was no such settings in that webui..

Do you know what other type of modeswitch command i can try?

Thanks

[stephenw10]

Not really, it's often a custom command. Check the usb-modeswitch forum.

@stephenw10 Thanks, i will check there.
