Possible values of an option:
From [2 USB Ports] to [8 USB Ports] or [12 USB Ports], [Disabled]
[8 USB Ports], [Disabled]
[Both], [Primary], [Disabled]
The option description:
The option is responsible for the standard USB-controller of a chipset. Value [Enabled] allows to involve this controller, [Disabled] — to disconnect it. Considering an USB-periphery large quantity, the controller should be necessarily included (value [Enabled]).
Regarding versions BIOS this option allows not only to include or switch off the standard USB-controller of a chipset, but also to specify number of the involved ports (their maximum quantity depends on a chipset). As switching-off of a part of USB-ports does not bring any dividends, choose for this option the greatest of accessible values (it can be a variant [12 USB Ports], [8 USB Ports] or, say, [Both]).
