 89           "high speed" (480 Mbit/sec, 60 Mbyte/sec) host controller hardware.
 90           If your USB host controller supports USB 2.0, you will likely want to
 91           configure this Host Controller Driver.
 92 
 93           EHCI controllers are packaged with "companion" host controllers (OHCI
 94           or UHCI) to handle USB 1.1 devices connected to root hub ports.  Ports
 95           will connect to EHCI if the device is high speed, otherwise they
 96           connect to a companion controller.  If you configure EHCI, you should
 97           probably configure the OHCI (for NEC and some other vendors) USB Host
 98           Controller Driver or UHCI (for Via motherboards) Host Controller
 99           Driver too.

401           The Open Host Controller Interface (OHCI) is a standard for accessing
402           USB 1.1 host controller hardware.  It does more in hardware than Intel's

404           say Y.  On most non-x86 systems, and on x86 hardware that's not using a
405           USB controller from Intel or VIA, this is appropriate.  If your host
406           controller doesn't use PCI, this is probably appropriate.  For a PCI
407           based system where you're not sure, the "lspci -v" entry will list the

802           Say 'Y' to enable additional software test modes that may be
803           supported by the host controller drivers.
804 
805           One such test mode is the Embedded High-speed Host Electrical Test
806           (EHSET) for EHCI host controller hardware, specifically the "Single
807           Step Set Feature" test.  Typically this will be enabled for On-the-Go
808           or embedded hosts that need to undergo USB-IF compliance testing with
809           the aid of special testing hardware.  In the future, this may expand
810           to include other tests that require support from a HCD driver.
811 
812           This option is of interest only to developers who need to validate
813           their USB hardware designs.  It is not needed for normal use.  If
814           unsure, say N.
