My changes to the example program are to change line 28 to "Keyboard.begin()" and line 53 to "Keyboard.println("Hello World!");" Seems like it should work but no go. One thing I notice is that the Windows Device Manager doesn't show the Trinkey in the "Keyboards" group (but does list it in the "Human Interface Devices" group). Could it be that the device is not properly reporting itself as a keyboard?
