PIO USB require CPU clock must be multiple of 120 Mhz - is that true or 12 MHz?

I think it's 120 Mhz, but honestly I am not 100%, nor do I know the reason for the limitation. The code here seems to enforce it though: https://github.com/FoamyGuy/Adafruit_Learning_System_Guides/blob/7edbbf2401b81734db129807f714c056cba07048/USB_SNES_Gamepad/Arduino_USB_Host/usbh_helper.h#L68

Please check with Scott, I was thinking this was an evolving thing

Also look to use a .test.only file for Arduino projects https://learn.adafruit.com/submitting-arduino-code-to-the-adafruit-learning-system
