Description

Hello. I am trying to create a usb device and I need to disable the CDC so that only the hid device works.
To install the code, I use usbasp. After enabling the -DC DC_DISABLED parameter or adding define, the CRC still works and I get a hid device plus a non-working device.
Does anyone know the solution to this problem?

Research direction

Start by checking how the Arduino AVR core handles the CDC_DISABLED define and how the usbasp build receives the -D option. Reproduce the USB configuration with CDC disabled and HID enabled; done means the device exposes HID without an additional CDC device.
