Don't own a RPI4 just a RPI3. Hmmmm...I wonder?

}Which mouse/keyboard? Normal or pro g?@KurtE - Just setup TD1.58B2. I have a library called TeensyMiniOS that I have been playing with for testing. When I added TeensyEXT4V3 to it with TD1.57 I ran out of memory for local variables to the tune of 15k bytes. Recompiling it with TD1.58B2 it was +23K so it is more memory efficient
Edit - This is with a Logitech wireless mouse and keyboard. Moving the mouse sketch shows keypresses and left button shows keypress and release 1, right button 2.
