Your config has: # CONFIG_USB_SUPPORT is not set CONFIG_USB=m That combination should not be possible, because in drivers/usb/Kconfig, the definition of USB is inside an "if USB_SUPPORT" block. Runing "make oldconfig" shows that this happened because: warning: (MOUSE_APPLETOUCH && MOUSE_BCM5974 && MOUSE_SYNAPTICS_USB && JOYSTICK_XPAD && TABLET_USB_ACECAD && TABLET_USB_AIPTEK && TABLET_USB_HANWANG && TABLET_USB_KBTAB && TABLET_USB_WACOM && TOUCHSCREEN_USB_COMPOSITE && INPUT_ATI_REMOTE2 && INPUT_KEYSPAN_REMOTE && INPUT_POWERMATE && INPUT_YEALINK && INPUT_CM109 && RC_ATI_REMOTE && IR_IMON && IR_MCEUSB && IR_REDRAT3 && IR_STREAMZAP && IR_IGUANA && DRM_USB) selects USB which has unmet direct dependencies (USB_SUPPORT && USB_ARCH_HAS_HCD) The culprit is DRM_USB, and I think Greg has just accepted a patch to fix it.
