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...
