75 The Open Host Controller Interface (OHCI) is a standard for accessing
76 USB 1.1 host controller hardware. It does more in hardware than Intel's
78 say Y. On most non-x86 systems, and on x86 hardware that's not using a
79 USB controller from Intel or VIA, this is appropriate. If your host
80 controller doesn't use PCI, this is probably appropriate. For a PCI
82 right "prog-if" for your USB controller(s): EHCI, OHCI, or UHCI.

91 The Universal Host Controller Interface is a standard by Intel for
92 accessing the USB hardware in the PC (which is also called the USB
93 host controller). If your USB host controller conforms to this
94 standard, you may want to say Y, but see below. All recent boards
95 with Intel PCI chipsets (like intel 430TX, 440FX, 440LX, 440BX,
96 i810, i820) conform to this standard. Also all VIA PCI chipsets
97 (like VIA VP2, VP3, MVP3, Apollo Pro, Apollo Pro II or Apollo Pro
98 133). If unsure, say Y.
