I see qualcomm's inf file that has this %xxx% =

USB\VID_1234&PID_3333&MI_02 xxx% = QportInstalltest,
USB\VID_1234&PID_3333&MI_00 all this three has same VID&PID, diff only
on MI. what does MI means? It seems that host locate driver not only
throught vid&pid, what is the rule, i can't find it in specification.
Some info on Windows USB identifiers for the curious:

The MI_xx part matches against the bInterfaceNumber of the interface
descriptor for a composite device. It allows Windows to perform a
separate hardware device installation for each interface of the
composite device.
