We also get five USB uarts if we add the device id with something
like the patch below. I don't quite get why we get five UARTS?

Also not sure if we should be using drivers/usb/serial/qcaux.c
instead of qcserial.c?

And from what I recall trying it out, adding the USB UARTs
somehow confused ModemManager I think, that needs to be retested
though :)

And the USB UARTs added do not offer the same set of AT commands
as the n_gsm serial mux.
