Describe the Bug
If you build qmk with EXTRAKEY_ENABLE which is default your keyboard will report that is supporting every HID available which will break steaminput. https://github.com/qmk/qmk_firmware/blob/02517bd8069ea6d22a3b10945611b0170f7ef7d4/tmk_core/protocol/usb_descriptor.c#L344-L347
Steam and KDE system settings will also detect your keyboard as joystick / gamepad.
For example my dualshock 4 controller will stop working in Dark souls 2 if I connect QMK keyboard. For now I have moved back to stock firmware which doesn't have this issue.
