My projects seem to require different profiles than are provided... I've already hacked a joystick only profile (from the USB HID profile that also included a keyboard and mouse) but now I need to communicate with Teensy 3.1 based MIDI device via a virtual COM port. This is due to a limitation in some desktop software that is being used.
I've taken a stab at combining the serial and MIDI profiles with no luck so far. I started with the MIDI profile and updated usb.c to copy some descriptor entries etc from the serial-only profile's usb.c. usb_private.c also needed some #defines. My prior experience was several days of trial and error and I'm reluctant to stumble so blindly through it again.
Anyone have any pointers on how to achieve this goal? Maybe someone has already undertaken this project?
My backup is to just use two Teensys. This is a waste but I suppose $20 is a lot cheaper than spending a week mucking about with code.
