I recently installed 2008 R2 on a Dell PowerEdge R220 and after the installation finished, my M&K inputs won't work. I read on here that the USB 3.0 settings could be enabled and I should disable them since the drivers are more than likely not installed.  However, I cannot find the settings to disable 3.0 for the life of me.

I enter the BIOS (F2) and go to the System Setup portion. Inside there I look at Integrated Devices but I don't see anything in that part that says anything about enabling/disabling USB 3.0. 

Any help would be greatly appreciated. Thanks!
