23 bool "EHCI HCD (USB 2.0) support"
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.
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
