 39           If your USB host controller supports USB 2.0, you will likely want to
 40           configure this Host Controller Driver.
 41 
 42           EHCI controllers are packaged with "companion" host controllers (OHCI
 43           or UHCI) to handle USB 1.1 devices connected to root hub ports.  Ports
 44           will connect to EHCI if the device is high speed, otherwise they
 45           connect to a companion controller.  If you configure EHCI, you should
 46           probably configure the OHCI (for NEC and some other vendors) USB Host
 47           Controller Driver or UHCI (for Via motherboards) Host Controller
 48           Driver too.

 59           Some EHCI chips have vendor-specific extensions to integrate
 60           transaction translators, so that no OHCI or UHCI companion
 61           controller is needed.  It's safe to say "y" even if your
 62           controller doesn't support this feature.
