I feel like I might have one more idea on why this could be happening, in the current usbMIDI implementation none of the midi ports have their own names so it relies on Windows to come up with one on its own. So what could be happening is it sees they have the same PID so it just picks one of them to generate a name from for both devices. And now that I mention it I do remember that I gave my ports they’re own names back when I first programmed 3 Teensy 3.6s that are on a Windows 7 machine. I’m pretty sure they don’t have any issues last time I checked, but it’s definitely something else to look into, if anyone wants a place to start with this here’s the thread from 2 years ago: https://forum.pjrc.com/threads/50043-Configurable-usbMIDI-Port-Names I haven’t messed with it since then so it probably would need to be updated.
