+	---help---
+	  The Enhanced Host Controller Interface (EHCI) is standard for USB 2.0
+	  "high speed" (480 Mbit/sec, 60 Mbyte/sec) host controller hardware.
+	  If your USB host controller supports USB 2.0, you will likely want to
+	  configure this Host Controller Driver.
+
+	  EHCI controllers are packaged with "companion" host controllers (OHCI
+	  or UHCI) to handle USB 1.1 devices connected to root hub ports.  Ports
+	  will connect to EHCI if the device is high speed, otherwise they
+	  connect to a companion controller.  If you configure EHCI, you should
+	  probably configure the OHCI (for NEC and some other vendors) USB Host
+	  Controller Driver or UHCI (for Via motherboards) Host Controller
+	  Driver too.
+
+	  You may want to read <file:Documentation/usb/ehci.txt>.
