+config USB_EHCI_HCD
+ bool "EHCI HCD (USB 2.0) support"
+ ---help---
+ The Enhanced Host Controller Interface (EHCI) is standard for USB 2.0
+ "high speed" (480 Mbit/sec, 60 Mbyte/sec) host controller hardware.
+ If your USB host controller supports USB 2.0, you will likely want to
+ configure this Host Controller Driver.
+
+ EHCI controllers are packaged with "companion" host controllers (OHCI
+ or UHCI) to handle USB 1.1 devices connected to root hub ports. Ports
+ will connect to EHCI if the device is high speed, otherwise they
+ connect to a companion controller. If you configure EHCI, you should
+ probably configure the OHCI (for NEC and some other vendors) USB Host
+ Controller Driver or UHCI (for Via motherboards) Host Controller
+ Driver too.
+
+ You may want to read <file:Documentation/usb/ehci.txt>.
