If the "AT" command gives you an "OK", you found the correct device. Note the modem exposes four UARTs. If this all is the case, a USB serial driver that exposes a terminal session  (like PL2303 [1]) is needed on Genode. I don't know exactly what kind of USB UART adapter the modem exposes right now. Maybe it's already PL2303. I will check.

Booting Ubuntu on the device (/dev/ttyUSB2) to be driven by the option serial driver (drivers/usb/serial/option.c). I did not check, which other files are required to create a working driver thou.

I will try to expand `usb_terminal` to support both types of serial ports.
