    USB legacy is supported..( does that mean that port s enabled /)
  5. USB Legacy means that USB keyboard behave as if they were PS/2 keyboard (the older connectors before USB mice and keyboard came out). Its usually to make them work under DOS and older Windows versions.

    To check if USB is really enabled, you need to enter your BIOS. Normally that's done by hitting the DEL or F1/F2 key right after you power on the computer. Check your manual for the exact key. In the BIOS menu look for "Integrated Devices" or wander around in the menu's until you see something about USB being enabled or not. Something like:

    USB support: [enabled]
    USB 2.0 support: [enabled]
    USB Legacy support: [enabled]
