Send AT Command to module that is not working as HOST (does not show /dev/ttyUSB paths)

Question

I was doing some experiments with a 5G module (STIM8200EA-M2) and sent the AT+CPCIEMODE=PE that set the module to PE mode (I don't know what is the meaning of that).

The problem is that now I can't see the module in the traditional /dev/ttyUSB* paths, witch means I can't connect to it with minicom and reverse what I did (set it back as HOST).

How can I send a single AT command for this situation?

Answer 1

I end up finding out how to get back the /dev/ttyUSB* ports. I had to add the module ID to the USB serial drivers.

With lsusb you can get the ID and then in root mode you just do:

echo "05c6 901f" > /sys/bus/usb-serial/drivers/generic/new_id

(replace the : from the ID with a whitespace)
