I am not really bound to this, but I just did play with it. From within
oFono we would be even capable in running the modem via libusb, but with
ModemManager you are a bit more limited and tight to a TTY.
You'd perhaps want to present it as a network interface for the network
side of stuff in that mode ?
Once the firmware has been loaded, the device provides multiple
endpoints. One of those works as a serial UART, one is a debug port of
some description, one is another serial UART for GPS information (though
I haven't figured out how to turn that on yet) and the last is a custom
and undocumented CDC interface. If we knew how to drive the hardware
properly, a kernel driver would be the obvious implementation.
After a bit of confusion from the windows driver logs, I've gotten the
firmware loaded in Linux with both generic usbserial and a modified
qcserial (Just the alt setting has changed). The modem device works
very nicely again with both generic usbserial and qcserial, but there's
some oddities with the device. lsusb output attached (The same is true
even if it was the windows drivers that loads the firmware). Any idea
what the 'UNRECOGNIZED' things are?
Going to try get GPS working tomorrow...
