### Details

Is this keyboard too ancient to be able to be supported? I can't even use modern logi options for it, it needs the logitech gaming app 😆

Start by reproducing `openlogi list` and `openlogi diag features` with the wired G710+ connected; the issue provides no feature output for the keyboard. Read the running agent's device-discovery path and determine what device information and behavior are required for G710+ support. Done means the keyboard is recognized and its supported functionality is exposed, but the issue does not define that functionality.
