6.4.2 Command 0x1F02 - Set Notification Subscriptions

The host uses this command to specify which notifications the device should send on each of its available
interfaces. By default, the device sends notifications to the host on all interfaces.
The sequence of events is as follows:
1) The host constructs the command request in the format below.
2) The host sends the command request to the device.
3) The device sends a response in the format below to the host.
4) The device immediately begins routing notifications per the request.
5) If the device restarts or loses power, the device resets its notification subscriptions to defaults, and the
host must call this command again to change them.
