    Teensy not being recognized as MIDI device (showing up as generic usb audio)

    I am fairly new to Teensy but I've done 4 projects already using usb type = midi with no problems. Just started my 5th project and for whatever reason, no matter what I do my Teensy is being recognized (in windows 10) as a "Generic USB Audio" device. I did some searching on here and haven't found anything that looks like this problem. To keep things simple I have just been trying the USB Midi example such as the buttons example and name examples, they both do the same thing. I have tried deleting the device from device manager, I have tried two other windows machines and the Teensy is recognized as a "Generic USB Audio" device on those machines as well. I have been using Arduino 1.8.5 and tried downgrading to 1.8.4 which made no difference. I have tried manually uploading the program to the Teensy and nothing seems to make any difference. Any help would be greatly appreciated!

    In Windows USB info is cached and not updated on each load. Reboot your PC between connection attempts.

    At least that's what I recall. No expert at USB
