 In the files

arch/ia64/kdb/kdba_io.c
arch/x86/kdb/kdba_io_32.c
arch/x86/kdb/kdba_io_64.c

 poll_funcs[] is set like so:

get_char_func poll_funcs[] = {
#if defined(CONFIG_VT_CONSOLE)
        get_kbd_char,
#endif
#if defined(CONFIG_SERIAL_CONSOLE) 
        get_serial_char,
#endif  
#ifdef  KDB_BLINK_LED
        blink_led,
#endif
#ifdef  CONFIG_KDB_USB
        get_usb_char,      <<<< here
#endif
        NULL
};


 kdb/kdb_io.c:kdb_read() uses poll_funcs[] to get chars...
