  11           The Enhanced Host Controller Interface (EHCI) is standard for USB 2.0
  12           "high speed" (480 Mbit/sec, 60 Mbyte/sec) host controller hardware.
  13           If your USB host controller supports USB 2.0, you will likely want to
  14           configure this Host Controller Driver.  At the time of this writing,
  15           the primary implementation of EHCI is a chip from NEC, widely available
  16           in add-on PCI cards, but implementations are in the works from other
  17           vendors including Intel and Philips.  Motherboard support is appearing.
  18
  19           EHCI controllers are packaged with "companion" host controllers (OHCI
  20           or UHCI) to handle USB 1.1 devices connected to root hub ports.  Ports
  21           will connect to EHCI if the device is high speed, otherwise they
  22           connect to a companion controller.  If you configure EHCI, you should
  23           probably configure the OHCI (for NEC and some other vendors) USB Host
  24           Controller Driver or UHCI (for Via motherboards) Host Controller
  25           Driver too.
  26

  35         ---help---
  36           Some EHCI chips have vendor-specific extensions to integrate
  37           transaction translators, so that no OHCI or UHCI companion
  38           controller is needed.  It's safe to say "y" even if your
  39           controller doesn't support this feature.
  40
  41           This supports the EHCI implementation that's originally
  42           from ARC, and has since changed hands a few times.

  48           This changes the periodic scheduling code to fill more of the low
  49           and full speed bandwidth available from the Transaction Translator
  50           (TT) in USB 2.0 hubs.  Without this, only one transfer will be
  51           issued in each microframe, significantly reducing the number of
  52           periodic low/fullspeed transfers possible.
  53
  54           If you have multiple periodic low/fullspeed devices connected to a
  55           highspeed USB hub which is connected to a highspeed USB Host

 130           The Open Host Controller Interface (OHCI) is a standard for accessing
 131           USB 1.1 host controller hardware.  It does more in hardware than Intel's
 132           UHCI specification.  If your USB host controller follows the OHCI spec,
 133           say Y.  On most non-x86 systems, and on x86 hardware that's not using a
 134           USB controller from Intel or VIA, this is appropriate.  If your host
 135           controller doesn't use PCI, this is probably appropriate.  For a PCI
 136           based system where you're not sure, the "lspci -v" entry will list the
 137           right "prog-if" for your USB controller(s):  EHCI, OHCI, or UHCI.
