 **   FILE NAME       : ifxusb_driver.c
 **   PROJECT         : IFX USB sub-system V3
 **   MODULES         : IFX USB sub-system Host and Device driver
 **   SRC VERSION     : 1.0
 **   DATE            : 1/Jan/2009
 **   AUTHOR          : Chen, Howard
 **   DESCRIPTION     : The provides the initialization and cleanup entry
 **                     points for the IFX USB driver. This module can be
 **                     dynamically loaded with insmod command or built-in
 **                     with kernel. When loaded or executed the ifxusb_driver_init
 **                     function is called. When the module is removed (using rmmod),
 **                     the ifxusb_driver_cleanup function is called.
