Open device manager: Right click My Computer | Properties | Hardware | Device Manager. Expand the Universal Serial Bus Controllers section. One should include the words, "Enhanced Host Controller". Double click it, click on Driver, Driver Details. one of the drivers should be usbehci.sys. Note you could have a mixture - some USB1 and some USB2.
