If they are working, then no.

This is normal. This is because the keycodes are above 128 and that's
all that you can fit into a single signed byte.

This is also normal and can be fixed via the setkeycodes utility. The

because their scancodes conflict. On USB the configuration is static,
because USB carries much more information about the keys.
