Non-standard clock rate for Pro Trinket detected

[Gamerto1212]

I ordered 3 Adafruit trinkets M0's, and started to make little projects. Im not verry setteld with micro controllers, but i have an idea how they work and what you need. So, i was making this: https://learn.adafruit.com/trinket-usb-volume-knob/code
I did the wiring, installed the librarys, selected the correct board in the Ardunio IDE, and copied the code into the IDE. some libraries are twice included, i will get rid of duplicates later. how erver, i trid to compile / verify the code, and it gave me this error:

In file included from C:\Users\William\Documents\Arduino\sketch_jun12a\sketch_jun12a.ino:3:
C:\Users\William\Documents\Arduino\libraries\Pro_Trinket_USB_Keyboard_Library/usbconfig.h:59:2: error: #error "Non-standard clock rate for Pro Trinket detected"
59 | #error "Non-standard clock rate for Pro Trinket detected"
| ^~~~~
I dont know why it says for Pro Trinket, but with this error i cant load the program on the Trinket. I did some research, but i couldnt find anything that helped me. So now im asking people who are more into this and are able to help me. If i should add any information, just comment it and i will try to provide ist ASAP.

Thanks for your efforts.

That project uses the "Pro Trinket USB Keyboard Library" which, as the name says, is for the Pro Trinket... not the Trinket M0.

Have a look at https://learn.adafruit.com/media-dial for a comparable project using the Trinket M0.
