Hi!
MHI Host Interface is a communication protocol to be used by the host
to control and communcate with modem over a high speed peripheral bus.
This module will allow host to communicate with external devices that
support MHI protocol.
I have Motorola Droid 4 cellphone here, with Qualcomm GSM modem. But
it talks over serial line and USB. I guess MHI is not applicable to my
hardware?
MHI is for PCIe based modem, in any case I can't comment about
commercial devices.

What kind of protocol is running over MHI? I guess its not AT
commands. QMI? Or something entirely different?
All modem services between external modem and host go over MHI.
So QMI, AT, all other data and control services go thru MHI host driver.
