Are you trying to force host only mode? I started anew from omap2plus_defconfig and applied the following changes to enable NFS root. -CONFIG_USB_NET_DRIVERS=m -CONFIG_USB_USBNET=m -CONFIG_USB_NET_SMSC95XX=m -CONFIG_USB=m -CONFIG_USB_EHCI_HCD=m -CONFIG_USB_EHCI_HCD_OMAP=m -CONFIG_NOP_USB_XCEIV=m -CONFIG_USB_GADGET=m -CONFIG_OMAP_USB2=m +CONFIG_USB_NET_DRIVERS=y +CONFIG_USB_USBNET=y +CONFIG_USB_NET_SMSC95XX=y +CONFIG_USB=y +CONFIG_USB_EHCI_HCD=y +CONFIG_USB_EHCI_HCD_OMAP=y +CONFIG_NOP_USB_XCEIV=y +# CONFIG_USB_GADGET is not set +CONFIG_OMAP_USB2=y I had to disable CONFIG_USB_GADGET is compiling it as a module prevents selecting CONFIG_NOP_USB_XCEIV=y, which is a dependency for CONFIG_USB_EHCI_HCD_OMAP=m. The new configuration resulted in a few changes, among which the most notable is -# CONFIG_USB_MUSB_HOST is not set -# CONFIG_USB_MUSB_GADGET is not set -CONFIG_USB_MUSB_DUAL_ROLE=y +CONFIG_USB_MUSB_HOST=y I then get the same error as originally reported. -- 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
