This is what the version 2.5.2 adds to dmesg:

I use Slackware's built-in package:

ftp://ftp.slackware.com/pub/slackware/s ... odeswitch/

I am not sure if it is Slackware's or usb_modeswitch's problem, so I'm reporting it in both places.

Please paste the output from:

sudo lsusb -v -d 19d2:1282


19d2:1421 did not have a device switch file in the past so this is caused by the latest usb_modeswitch.
I don't understand how you got it to switch into 19d2:0017 previously, there is an indication of a power reset in your log which seems related to the switching.
19d2:0017 after switching doesn't seem right to me even if the modem was working after entering that id..

[s]The output is literally empty.
[/s] UPD: my bad, did that after the switch has already done its job

We'll get to that later on.
Your lsusb listing shows strong similarities between the interfaces in 19d2:0017 and 19d2:1282 so your problem is likely that the latter has not been included in the qmi_wwan driver.
The option driver for the 19d2:1282 serial ports does also attach to the wrong interfaces..

19d2:0017 is an id used for debug and firmware update and you often continue to get there if a firmware update or modem unlock has not fully set the modem back to non-debug mode.
I'd prefer to see this modem being supported under the 19d2:1282 id if we can't find any other id apart from 19d2:0017 that we can switch it into..

So first step would be to see if there is any other switching methods for the modem and we can do that by modifying the 19d2:1421 device config file.
Find that file in the /usr/share/usb_modeswitch/configPack.tar.gz and copy it to the usb_modeswitch "override" directory
/etc/usb_modeswitch.d/.
You can now test different switch methods/messages by editing that file while keeping the file in the pack in original shape.

Try these contents in the file:

StandardEject=1
MessageContent="55534243123456702000000080000c85010101180101010101000000000000"

or

only the StandardEject line without any MessageContent

Replug the modem after each change and check what usb id you get after switching has taken place.
I'd guess that the single StandardEject line will bring you to 19d2:0017 but want to get that confirmed, and I'm curious to see what the combined switch method creates!


btw, what is the ZTE model number of this modem? MF733V? MF860?

Edit: Please also post the verbose lsusb list for the initial device id 19d2:1421, I want to see if there is more than one configuration to select between (could be an mbim configuration included).

Got it, I'll try to do this after work.

In fact, this is not an "official" ZTE modem, it's branded as Softbank (And I don't read any Japanese). However, it has a ZTE chip inside.

The model is 403ZT.

It switches to 19d2:0017

The modem works.

UPD: I cannot check whether 19d2:1421's lsusb, because after I insert it, it automatically switches to 19d2:0017.

I double-checked this by _completely uninstalling_ usb_modeswitch. So the following lines appear in dmesg _without usb_modeswitch installed_

I tried to reboot with init=/bin/sh, but lsusb doesn't work then, so I don't know how to check 19d2:1421

Is there any other way I can check lsusb before the device changes its id?

In fact, this is not an "official" ZTE modem, it's branded as Softbank (And I don't read any Japanese). However, it has a ZTE chip inside.

The model is 403ZT.
I have downloaded Softbanks Switchtool for 403ZT from their support site and installed it under Windows.
Apart from the actual switch program it also installed the drivers and from them it is clear that the switched usb id should be 19d2:1282.

The option drivers in linux has to be corrected and the id has to be included in the qmi_wwan driver for a future linux release so I suggest that you continue to switch it into 19d2:0017 by keeping the 19d2:1421 device config file in the override directory with the single line StandardEject=1.
