-                        Comma-separated list of identifiers for input devices to be relayed. An identifier is either the input device path, the MAC address or any case-insensitive substring of the device name. Default is None. Example: --device_ids '/dev/input/event2,a1:b2:c3:d4:e5:f6,0A-1B-2C-3D-4E-5F,logi'
