    Creating a USB MIDI descriptor

    cheche_romo_1574446

      Hello everyone, I'm trying to create my first USB compliant device, specifically I'm trying to make an USB MIDI device, that can handle 4 MIDI Outputs.

       

      I I'm really lost when It comes to USB communication, I understand the basics, but I as said this is my first USB device. I got the device to show up on the computer, it connects as a MIDI Device, but with no ports available.

       

      I'm pretty sure my descriptor is all messed up, I tried using an endpoint for each out port, but I cant get it working.

      This is what my computer shows.

       

      Can someone help me understand how to create a proper descriptor for USB MIDI devices?? Thanks!
