Commands (input data for EnableJoyPollingReceiveMode / SendAndReceive) start with the u32 cmd, there's generally no data after that. Data in the replies are at least 0x4-bytes, with fields being 4-byte aligned. Reply+0 is the u8 status. When the output size doesn't match the expected size, or status is non-zero, error 0xEDA is returned. When status is non-zero, a func is called with the status value which updates global state.

The status field is not listed below since all replies have it.

This is used with EnableJoyPollingReceiveMode/GetJoyPollingReceivedData. Reply+0x4 is an u16 which is copied to an output struct, the [[HID_services#JoyPollingReceivedData|timestamp]] is also copied.
