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.

It does more in hardware than Intel's UHCI specification. If your USB host controller follows the OHCI spec, say Y. On most non-x86 systems, and on x86 hardware that's not using a USB controller from Intel or VIA, this is appropriate. If your host controller doesn't use PCI, this is probably appropriate. For a PCI based system where you're not sure, the "lspci -v" entry will list the right "prog-if" for your USB controller(s): EHCI, OHCI, or UHCI. if USB_OHCI_HCD config USB_OHCI_GENERIC bool "Support for generic OHCI USB controller" depends on OF_CONTROL depends on DM_USB select USB_HOST ---help--- Enables support for generic OHCI controller. endif # USB_OHCI_HCD config USB_UHCI_HCD bool "UHCI HCD (most Intel and VIA) support" select USB_HOST ---help--- The Universal Host Controller Interface is a standard by Intel for accessing the USB hardware in the PC (which is also called the USB host controller). If your USB host controller conforms to this standard, you may want to say Y, but see below. All recent boards with Intel PCI chipsets (like intel 430TX, 440FX, 440LX, 440BX, i810, i820) conform to this standard. Also all VIA PCI chipsets (like VIA VP2, VP3, MVP3, Apollo Pro, Apollo Pro II or Apollo Pro 133) and LEON/GRLIB SoCs with the GRUSBHC controller. If unsure, say Y. if USB_UHCI_HCD endif # USB_UHCI_HCD
