All recent boards 182 with Intel PCI chipsets (like intel 430TX, 440FX, 440LX, 440BX, 183 i810, i820) conform to this standard. Also all VIA PCI chipsets 184 (like VIA VP2, VP3, MVP3, Apollo Pro, Apollo Pro II or Apollo Pro 185 133) and LEON/GRLIB SoCs with the GRUSBHC controller. 186 If unsure, say Y. 187 188if USB_UHCI_HCD 189 190endif # USB_UHCI_HCD 191
