Apple Keyboard with Numeric Keypad MB110LL/B

Can't find software update on Apple/support/downloads/keyboards all the software updates are for wireless and on my MacPro with OSX 10.7.2 in System Pref.>keyboard>Change keyboard type it doesn't recognize keyboard? The keyboard works fine with the exception of some of the function keys setup for ITunes or Quicktime to play, rewind volume up or down and such. One of the reasons I bought this along with the fact it had numeric keypad.

Thanks for the help WMayne

THere are no updates for a wired keyboard

go to System preferences > Keyboard and select Change keyboard type

That should let the mac correctly identify the keybaord
