Cannot differentiate between LEFT ⌘ (0x37) and RIGHT ⌘ (0x36) keys

Question

I would like to swap the right-⌘ key with the right-⌥ key.

KeyRemap4MacBook's EventViewer shows that Alt Gr key acts as the left-⌘ (Command_L in EventViewer), whereas I'd like to be the right-⌘ (Command_R).

This is what it look like in EventViewer: first 2 lines are from left-⌘, next 2 lines are from right-⌘ (with the same 0x37 code):

How can I get the right-⌘ key to register as Command_R (0x36) instead of Command_L (0x37)?

About the keyboard

It's the Microsoft Natural Ergonomic Keyboard 4000 with its drivers installed and setup like this:

I'll try my luck with uninstalling the drivers (which don't cause kernel panics anymore, as described here).

Answer 1

Why didn't it try this before? Removing Microsoft's drivers was the solution! Right-ALT now acts as Option_R out-of-the-box (and isn't affected by swapping CMD/ALT with OPTION/Windows key on the left side).

Answer 2

Hopefully I misunderstood the question, but did you, um, try remapping them?

<root>
  <item>
    <name>Swap Command_L and Command_R </name>
    <identifier>private.swap_command_l_and_r</identifier>
    <autogen>__KeyToKey__ KeyCode::COMMAND_R, KeyCode::COMMAND_L</autogen>
    <autogen>__KeyToKey__ KeyCode::COMMAND_L, KeyCode::COMMAND_R</autogen>
  </item>
</root>

If the problem is that you are not using a Mac keyboard and both L and R are sending the same Keycode, then, as stated in the KeyRempap4MacBook FAQ:

If you are using [non-Apple] vendor's keyboard drivers, KeyRemap4MacBook may not work properly. Please uninstall vendor's keyboard drivers.
