EXT_LUN
These bytes are used to specify the number of LUNs the device exposes to
the host. These bytes are also used for icon sharing by assigning more than
one LUN to a single icon. This is used in applications where the device
utilizes a combo socket and the OEM wishes to have only a single icon
displayed for one or more interfaces.
If this field is set to FF, the program assumes that you are using the default
value and icons will be configured per the default configuration.
