The problem is that from aplication can't handle 0xe0 scancode because mpc5xxx_translate function translates the scancode to a keycode, and to the aplication arrives for example 0x0a1b5b41 (up arrow) and inmediatly another 0x0a. For this efect I think mpc5xxx_translate function needs to evaluate 0xe0 scancode correctly.

Actually that Microsoft keyboard is working fine. A rare exception. ,-)
For more information see chapter 1.3 from here:

So basically you will have to handle those in the application level code.
