While the USB 2. 0 specification supports all speeds of devices, the EHCI controller only supports high speed USB devices. In order for full speed and low speed USB devices to work, they must be connected to the EHCI controller through a USB 2. UHCI or OHCI Controller. For newer PCs, most USB 2. PCs are downstream of a USB 2. This hub is connected to an EHCI controller. This allows the PCs USB 2. Super. Speed devices behave as high speed devices when connected to a 2. After the USB 2. 0 specification was released, PCs used a combination of host controllers in order to support all speeds of devices. A single USB 2. 0 port would be wired to two host controllers, an EHCI host controller and either a UHCI or OHCI host controller.
