Hi, I am pretty new to driver development. I need to write a driver for USB MIDI device. I read the DDK docs but it seems so that I am lost in all the models and and restrictions. There is a nice WDM USB sample in the DDK but what to do as next? How to create the MIDI ports and read write data to them? Could some of you more experienced ones help a bit?
