If legacy USB 2.0 is the same as Legacy USB it allows your USB keyboard to work before the operating systems take over. Disableing it will prevent a USB keyboard from working. Maybe in the BIOS. A BIOS is a collection of device drivers that allow parts of the computer to work as it boots. There's a video device driver so it can make pictures as it boots, keyboard drivers so you can type things as it boots. I use USB to PS/2 adaptors so I've not used usb.
This may mean you can't use the keyboard outside of windows, that is it you can't use it in the BIOS. Also some BIOS have seperate setting for the legacy USB keyboard and one for other devices. Only USB2.0 legacy needs to be turned off. Although Win 98 had the same problem with USB 1.
