 Endianness issues
 ------------------
 
-The LITTLEENDIAN #define determines if the 'swap_16' and 'swap_32'
-macros do byte swapping or not. But some cpus OHCI-controllers such as
-ppc4xx and mpc5xxx operate in little endian mode, so some extra ifdefs
-were necessary to make this work.

+The USB bus operates in little endian, but unfortunately there are
+OHCI controllers that operate in big endian such as ppc4xx. For these the
