-Remote keyboard is an experimental feature that allows for connecting another
-keyboard, macropad, numpad, or accessory without requiring an additional USB connection.
-The "remote keyboard" forwards its keystrokes using UART serial over TRRS. Dynamic VUSB 
-detect allows the keyboard automatically switch to host or remote mode depending on
-which is connected to the USB port.
-
-Possible functionality includes the ability to send data from the host to the remote using
-a reverse link, allowing for LED sync, configuration, and more data sharing between devices.
-This will require a new communication protocol, as the current one is limited.
