An Ack is transmitted by the device for every received command after it has been handled successfully. If additional responses are triggered by the command, they are transmitted after this Ack.

\subsection{ClearTrigger} \subsection{ClearTrigger}
This packet is used when multiple devices are synchronized over USB and can be transmitted in both directions. It has no payload. Synchronized devices must be logically organized in a closed loop. When a ClearTrigger packet is received from any devices in the loop it must be passed on to the next device in the loop.

When a ClearTrigger packet is received from any devices in the loop it must be passed on to the next device in the loop.
\subsection{StopStatusUpdates}
This packet instructs the device to stop sending automatically scheduled DeviceStatusV1 packets. Device status can still be requested explicitly via RequestDeviceStatus packets.
\subsection{StartStatusUpdates}
This packet instructs the device to start sending automatically scheduled DeviceStatusV1 packets. This restores default update behaviour if a StopStatusUpdates packet has previously been sent.
