nsyskbd.rpl is the system library that allows applications to use USB keyboards plugged in the WiiU USB ports

Prototype	Description
`char KBDSetup((void)connection_callback,(void)disconnection_callback,(void*)key_callback)`	Initializes the USB keyboard library and return 0 if successfull. connection and disconnection callback are called repectively at the connection or disconnection of an usb keyboard; key callback is called when some key event occurs (2 times: press and release)
`char KBDTeardown()`	Deinitializes the USB keyboard library and return 0 if the deinitialization was successfull
`char KBDInit((void)unknown,(void)connection_callback,(void)disconnection_callback,(void)key_callback);`	Pass arguments to KBDSetup (probably an old function left for compatibility); should returns 0 if successfull
`char KBDExit();`	Calls KBDTeardown() (probably an old function left for compatibility); should returns 0 if successfull

Prototype	Description
typedef struct { unsigned char ch; unsigned char scancode; unsigned int state; //1=press; 0=release; 3=keep pressing char unknown[4]; //? unsigned short UTF16; } key_state;	Used as argument of key_callback
