My device, a tp-link mr200, has an internal USB modem that is internally a Android device, and I understand this is not uncommon anymore nowadays. it has the /dev/cdc-wdm0 device, but I am unable to make it present additional /dev/ttyUSB devices.

However, all needed data is presented in JSON format through the uqmi utility, and I wonder since that utility is broader in use for all QMI devices if that is not also a good generic status exchange protocol.

some examples below, but first the raw USB data:

I use modem RM520N-GL. It creates device /dev/wwan0mbim0 that can be interact with. Other devices do not work.
Can you add support for uqmi for it?

Hi,

Currently I am not planning to add anything to the package.
I plan to rewrite the package to show more data, but what will come out of that I don't know.
