+The raw scan codes are available only on AT and PS/2 keyboards,
+and even then they are disabled unless the
+.B atkbd.softraw=0
+kernel parameter is used.
+When the raw scan codes are not available, the kernel uses a fixed built-in

+.BR setkeycodes (8)
+can affect the output of
+.B showkey

 .RE
 will assign the keycode 112 to it, and then loadkeys(1) can be used
 to define the function of this key.
+
+USB keyboards have standardized keycodes and
+.B setkeycodes
+doesn't affect them at all.

 .SH OPTIONS
 None.
 .SH BUGS
 The keycodes of X have nothing to do with those of Linux.
 Unusual keys can be made visible under Linux, but not under X.

+.B setkeycodes
+affects only the "first" input device

+If there is more than one such device,
+.B setkeycodes
+cannot change the mapping of other devices than the "first" one.
