+         Enable driver model for USB. The USB interface is then implemented
+         by the USB uclass. Multiple USB controllers of different types
+         (XHCI, EHCI) can be attached and used. The 'usb' command works as
+         normal. OCHI is not supported at present.
+
+         Much of the code is shared but with this option enabled the USB
+         uclass takes care of device enumeration. USB devices can be
+         declared with the USB_DEVICE() macro and will be automatically
+         probed when found on the bus.
