Hi all,

I am trying to enable 3g in a Linux OpenWrt 3.3.8. I am testing with ZTE MF 667 (19d2:1405) device which is not included in usb-modeswitch-data.

Code: Select all

Bus 001 Device 004: ID 19d2:1405 ZTE WCDMA Technologies MSM

I have tried to use 19d2:0154 configuration creating a new file for 19d2:1405, but I receive following:

Switching seemingly failed

Do you know what is conf I have to use to switch to modem?

Please, let me know if you need more information.

Thanks and Regards,

[LOM]

19d2:1405 is the id for an already switched device, you can not not switch it further.

Do you know how can stop switch for first time?

This is my dmesg output for this device:

At the end, it is not attached to ttyUSB0.

Why do you want to stop it from switching?
In its initial unswitched state there is only a cd-rom interface for installing windows drivers and connection manager from, it is of no use for linux.

This dongle does not have interfaces for ppp over serial, it is a direct ip ethernet dongle, it needs the cdc_ether driver which will create an additional eth device in your system.

Thanks, you are right.

I did not know "cdc_ether".
