I committed the code with a comment about that, thank for Michael 
van Elst for making it clear: USB scancodes 49 and 50 have the 
same translation in most encodings. Exceptions are pt and hu 
(and uk for altgr). I retained the wrong but usual value.

The JIS case is more troublesome:

ADB scancode 93 used to be emulated as USB scan code 100, which 
in backslash/bar in our jp encoding. The change is supposed to turn 
it into USB scancode 137, which should be the Yen but is backslash/bar
in jp encoding. At least it does not change.

ADB scancode 94 used to be emulated as USB scan code 45, which is
minus/equal in our jp encoding. The change is supposed to turn it into
USB scan code 135, which should be RO but is backslash/underscore in 
jp encoding. 

I disabled the autoconfiguration to JIS layout until someone can test 
it. One need to sysctl -w machdep.adbkbd0.emulate_usb=3 in order to
enable it. Feecback welcome.
