Hello! Wiki says that USB Legacy Support must be disabled by OS as soon as it initializes USB controller. But how to do it? |

That depends on the controller. UHCI has a simple register to disable SMI generation, while EHCI and XHCI have a semaphore to communicate with the firmware. Check the data sheets. |
