4.1 CIS disable my hotkey in Thinkpad SL

4.1 CIS disable my hotkey in Thinkpad SL, and I reinstall all drivers for hotkey, still useless, after I uninstall CIS 4.1, the hotkey showed in correct way.

When I push mute microphone or sounds buttons, the D+ showed, and I add them into trust application. But still in wrong way.

Would anybody help me out of this?

By the way: My OS is: Win 7[at]32.
