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

E3372-320, E8372-320 and other newer modems with firmware version 10.x.x.x try to automatically detect PC operating system (Linux/macOS or Windows) and switch the mode accordingly. This is done by detecting USB Get Max LUN request from the operating system to device's CD-ROM. Automatic switching cr...

Re: TEROW ROW02FD

I second LOM's argument. In the beginning of it all, I collected device names with the idea of building a complete brand name reference.

I dropped that idea along the way because I realized it wasn't feasible, with all the rebrandings popping up.

Re: E3372h-320 - switching works sometimes

Hmm, this suggestion should probably go to distribution maintainers.

What do you think? Should I add this modconf file to the usb_modeswitch distribution and explain the issue in the Changelog?

Re: e3372 not switching

Note that you have to run usb_modeswitch as "root" or with "sudo" when using it manually.

Re: HP lt4220 (Snapdragon X12 LTE)

I have posted the report that triggered the change with "change" (haha).

https://bugzilla.kernel.org/show_bug.cgi?id=209469#c16

I'll have to check how a switch back to "add" only will affect reboot behaviour.

Re: Vodafone K5161h (12d1:1591)

The easiest way is to copy an existing config file like "12d1:1583", put it in "/etc/usb_modeswitch.d" and change the name to "12d1:1591". That should make the modem switch the next time you insert it. To check if it worked, either run the "dmesg" command line...

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

This problem may also be power-supply-related. If the USB power is not reliable, a modem may reset itself just when it draws more power while starting transmission (connecting to the cell network). It is known to have happened on older Raspberry Pis and on mobile devices (e.g. Android phones via the...

Re: switching Huawei E8372 to 'stick mode' (for ppp use)

Is there a way to detect these new modems/firmwares, apart from the USB ID?

Re: Ma180 3g dongle - at commands during connected

You can only try to send AT commands to one of the other ttyUSB ports. Sometimes they provide a DIAG port where you can do all of what you listed.

From Linux, try the "minicom" application - example:
minicom -D /dev/ttyUsb1

Re: In general, did older devices change into modems; while newer ones, into Etherent?

Yes, you could say that. When wireless USB modems emerged, there wasn't much choice regarding drivers. So they mostly chose the USB simulation of a serial port, like it was used on analogue landline modems. The drivers and the overlaying tools (pppd) were widely available. However, that serial proto...

Re: UDEV rules problem with ifup

Newer versions of udev will kill subprocesses started by rules if they are running 'too long'. I suspect this is happening in your case. Standard usb_modeswitch installations are working around this by using a systemd service file. This allows the detachment of the mode-switching process from udev s...

Re: HP lt4220 (Snapdragon X12 LTE)

I have responded to the kernel bugzilla report. I'll see if I can pinpoint the reason why I introduced the "change" event in the udev rule.

Re: 1&1 ZTE MF710M fails to set up

Are you using a proper terminal program to issue AT commands?

I'm using "minicom" for this purpose.
