What is this Universal Controller of which you speak please? Or are you referring to a Universal System Bus Controller aka USB port?
Put simply: OHCI = USB 1.1. EHCI = USB 2.
As a general rule of thumb, a USB device capable of running at USB 2 speeds are usually capable of running at USB 1.1 speeds when plugged into non-USB 2 ports.
