My Yamaha P-95 Won't Show Up as a Midi Device

I was using my Yamaha P-95 as my midi keyboard in Logic 9, which I tested again today and it was fine so I know the midi ports on my keyboard are okay. I have upgraded to Logic Pro X and I'm trying to set up my keyboard as a midi device, but it looks like my new Mac Mini won't recognize it. I have it hooked up via a midi to USB-C cable, which seems to be working. In Logic, it says there is a USB Midi Interface under the Midi settings. But no matter what I do, I can't get a signal when I press the keys. Please help!
