The problem is that if I design a class-compliant driver, and two

started writing their own drivers after trying to design the device
class-compliant.
What's the use case where you need to know this? If you're connecting
up two MIDI devices with different capabilities, doesn't MIDI have
custom messages for reporting capabilities so you can tell the
difference that way? And if you connect up two identical MIDI devices,
why would it matter?
If they have serial numbers, you should be able to get the serial number
from the device name using the SetupDi APIs.
