In both cases 27 you need a low level bus controller driver, and some software 28 talking to it. Peripheral controllers are often discrete silicon, 29 or are integrated with the CPU in a microcontroller. The more 30 familiar host side controllers have names like "EHCI", "OHCI", 31 or "UHCI", and are usually integrated into southbridges on PC 32 motherboards. 33 34 Enable this configuration option if you want to run U-Boot inside 35 a USB peripheral device.
