+ The Open Host Controller Interface (OHCI) is a standard for accessing
+ USB 1.1 host controller hardware. 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.

+ 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.
