Default Value: The default value is no string with a length of zero.
Description: The value is an ASCII string that represents the device’s serial number. This
string can be 0 – 15 bytes long. The value of this property, if any, will be sent
to the host when the host requests the USB string descriptor.
This property is stored in non-volatile memory, so it will persist when the unit
is power cycled. When this property is changed, the unit must be reset (see
Command Number 2) or power cycled to have these changes take effect.
