// Bit 1 - Set if the device is enabled and decoding its resources.
// Bit 2 - Set if the device should be shown in the UI.
// Bit 3 - Set if the device is functioning properly (cleared if device failed its diagnostics).
// Bit 4 - Set if the battery is present.
// Bits 5-31 - Reserved (must be cleared).
