Hi Dmitry,

I am currently writing a "multi function device" driver for synology
NAS devices. They have an on-board chip that handles things like, leds,
fan speed, buzzer, proper shutdown/restart and button presses:

- Power button for shutdown

- Reset button for triggering a factory reset

- USB Copy button for transfering files between a usb stick (not
available on all devices).

With the exception of the Power button (KEY_POWER), I am not sure which
keycodes I should use for the buttons mentioned above in the driver.

What would you recommend?

Thanks
