If your USB host controller conforms to this 192 standard, you may want to say Y, but see below. All recent boards 193 with Intel PCI chipsets (like intel 430TX, 440FX, 440LX, 440BX, 194 i810, i820) conform to this standard. Also all VIA PCI chipsets 195 (like VIA VP2, VP3, MVP3, Apollo Pro, Apollo Pro II or Apollo Pro 196 133) and LEON/GRLIB SoCs with the GRUSBHC controller. 197 If unsure, say Y. 198 199if USB_UHCI_HCD 200 201endif # USB_UHCI_HCD 202
