config USB_XHCI_HCD

The eXtensible Host Controller Interface (xHCI) is standard for USB 3.0
"SuperSpeed" host controller hardware.

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>.
