Hello,

I have struggled now for several nights without success, my modem still shows up as storage device and dont attach to a device (ttyUSB*)

It seems like it switches from 12d1:157d to 12d1:14dc after I have used

Code: Select all

usb_modeswitch -W -v 12d1 -p 157d -V 12d1 -P 14dc -M ”55534243123456780000000000000011062000000101000100000000000000"

But still

Code: Select all

dmesg | grep USB 

shows

12d1:14dc is the correct id after switching, it contains a direct ethernet net device interface and a storage interface for the SD/TF card reader, there are no serial interfaces in this dongle so no ttyUSBx are created.
Load the cdc_ether driver and your dmesg will show binding of that driver and creation of a net device.
