Re: Help Needed to setup device id 161c:f101

When the device id is 161c:f101 then it is already switched (possibly by usb_modeswitch) and it can't be switched further. As you have noted there is a forum thread for this device under a different mfgr name but there was no final solution in it, the problem is unsolved. The net interface of the de...

Re: Huawei E5220 - wwan0 disappear until reboot - Ubuntu 20.04 LTS

There may be other problems remaining when you have got rid of the option driver from interface #0. I just realized that in your second usb-devices listing it only have one endpoint while in the first listing it has three (this is corrrect, the ncm driver needs three endpoints in order to bind). In ...

You can also download the Ubuntu usb-modeswitch package for "groovy" in which they finally have removed the driver loading from usb-modeswitch.

Re: Huawei E5220 - wwan0 disappear until reboot - Ubuntu 20.04 LTS

If you haven't done a manual bind of the option driver then there is only one possible reason left for why the option driver binds to the net interface and that is Ubuntu's modification of usb-modeswitch where they do driver loading for certain interfaces. This is something that was removed from gen...

Re: Huawei E5220 - wwan0 disappear until reboot - Ubuntu 20.04 LTS

The option driver is grabbing the net interface in the second plug-in, it does this only if you force it to load manually by using the new_id function.
Don't do that, when the option driver is loaded automagically then it knows to not take the net interface!

Re: Huawei E5220 - wwan0 disappear until reboot - Ubuntu 20.04 LTS

I don't think it is usb_modeswitch related, your log shows a successful modeswitch two times with the dongle going into standby/charge mode (12d1:1c20) in between them. You don't get a cdc_ncm driver binding the second time after leaving standby/charge mode but that is likely a linux driver problem....

Re: E3372h-320 (update 2020 version of E3372) automatically switches itself into ethernet mode

Oh, I'm probably wrong then. I saw some devices with "ethernet networking" as their subclass and assumed that it was actually using ethernet. Yes they are using the ethernet protocol which doesn't have a cmd language so it is not a good protocol for modems. Am I right in my assumption tha...

Re: E3372h-320 (update 2020 version of E3372) automatically switches itself into ethernet mode

An auto-switching Huawei modem like ZTE does for some of their modems, it would be the first for Huawei but it is not impossible. Ethernet mode is not for MS Windows which only speaks NDIS or MBIM, and it is not for linux which has better protocols like NCM, MBIM, and QMI. It is for Apple Mac which ...

Hey, I was wondering if you could help me with another issue, when i plug the device the interface shows up as wxx0c5b8f279a64. With it i can either set a static IP or fetch one from the device through dhclient and that's fine but when i boot the system the interface does not appear. I need to remo...

Re: Attempting to setup E5372s-32

Hey, Thanks for you help! After Josh reply i went to flash the firmware again and this time it is loading the id 12d1:1596 which is creating a ethernet interface. On that ethernet interface you will get a private IP address from within E5372 LAN where also the wifi clients will reside. The internal...

Re: Attempting to setup E5372s-32

12d1:1c05 is not an id that a working E5372 should get, it is a debug id which you have ended up with because something went wrong when you flashed it. The 3 serial interfaces are for testing, it is possible that the modem function (ttyUSB0) is fully working but you do at least need a ppp dial-up pr...

Re: Huawei E3372s-153

Your 1st switch cmd is successful, it switches the dongle from 12d1:1f01 to 12d1:14dc Your 2nd switch cmd fails because the dongle has already switched, it no longer has the usb id 12d1:1f01 Your 3rd switch cmd fails because you can not switch 12d1:14dc, that is the id after switching and you can no...
