24	---help---
25	  The Enhanced Host Controller Interface (EHCI) is standard for USB 2.0
26	  "high speed" (480 Mbit/sec, 60 Mbyte/sec) host controller hardware.
27	  If your USB host controller supports USB 2.0, you will likely want to
28	  configure this Host Controller Driver.
29
30	  EHCI controllers are packaged with "companion" host controllers (OHCI
31	  or UHCI) to handle USB 1.1 devices connected to root hub ports.  Ports
32	  will connect to EHCI if the device is high speed, otherwise they
33	  connect to a companion controller.  If you configure EHCI, you should
34	  probably configure the OHCI (for NEC and some other vendors) USB Host
35	  Controller Driver or UHCI (for Via motherboards) Host Controller
36	  Driver too.
