7.3.3 Command 0x02 - Reset Device (MAC)

This command is used to reset the device, and can be used to make property changes take effect without
power cycling the device.
(USB Only)
When resetting a device that is using the USB connection, the device automatically does a USB Detach
followed by an Attach. After the host sends this command to the device, it should close the USB port,
wait a few seconds for the operating system to handle the device detach followed by the attach, then re-
open the USB port before trying to communicate further with the device.
In rare instances, devices may optionally be configured at the manufacturer to require a MAC for every
Reset Device command call, not just when anti-hack behavior is active.
