The reason I went for host mode is that I had to disable CONFIG_USB_GADGET as compiling it as a module prevents selecting CONFIG_NOP_USB_XCEIV=y, which is a dependency for CONFIG_USB_EHCI_HCD_OMAP=m. config NOP_USB_XCEIV tristate "NOP USB Transceiver Driver" depends on USB_GADGET || !USB_GADGET # if USB_GADGET=m, NOP can't be built-in select USB_PHY -- Regards, Laurent Pinchart -- To unsubscribe from this list: send the line "unsubscribe linux-usb" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
