/* (Explanation and mac classes taken from WiiC)
* The different codes wrt. to Linux
* is a bit hard to explain.
* Looking at Bluetooth CoD format, we have 24 bits.
* In wiic Linux they are stored in three fields,
* each one 8bit long. The result number is
* 0x002504. However, MacOS Bluetooth does
* not store them in such a way, rather it uses
* the concept of major service, major class,
* and minor class, that are respectivelly
* 11bit, 5bit, and 6bit long. Hence, the
* numbers are different.
* The Wiimote CoD Bluetooth division is the following:
* 00000000001 00101 000001 00 (major service - major class - minor class - format type)
* This can also be seen in the WiiC Linux way:
* 00000000 00100101 00000100
