-Subject: [PATCH] Allow disabling CDC with -DCDC_DISABLED
-
-https://github.com/arduino/ArduinoCore-avr/pull/383
-
-Sometimes Arduino-based USB devices don't work because some hardware
-(like KVM switches) gets confused by the CDC sub-devices.
-This change makes it relatively easy to disable CDC at compiletime.
-Disabling it of course means that the serial console won't work anymore,
-so you need to use the reset button when flashing.
-
-CDC_DISABLED is also used in ArduinoCore-samd for the same purpose.
-
-based on
-https://github.com/gdsports/usb-metamorph/tree/master/USBSerPassThruLine
-
-See also https://github.com/NicoHood/HID/issues/225 and
