1添加drivers/media/video/uvc，（可以从网上下载linux-uvc_trunk_arne.tar.gz，然后修改，或者参见http://lwn.net/Articles/287912/及http://mxhaard.free.fr/download.html），内涵

Kconfig（自己添加） uvc_compat.h uvc_driver.c uvc_v4l2.c uvcvideo.h

Makefile（自己添加） uvc_ctrl.c uvc_queue.c uvc_video.c

其中Makefile内容为：

uvcvideo-objs := uvc_driver.o uvc_queue.o uvc_v4l2.o uvc_video.o uvc_ctrl.o
obj-$(CONFIG_USB_VIDEO_CLASS) += uvcvideo.o

其中Kconfig内容为：

config USB_VIDEO_CLASS
        tristate "USB Video Class (UVC)"
        ---help---
          Support for the USB Video Class (UVC). Currently only video
          input devices, such as webcams, are supported.

          For more information see: <http://linux-uvc.berlios.de/>

config USB_VIDEO_CLASS_INPUT_EVDEV
        bool "UVC input events device support"
        default y
        depends on USB_VIDEO_CLASS && INPUT
        ---help---
          This option makes USB Video Class devices register an input device
          to report button events.

          If you are in doubt, say Y.

2.在video的Makefile中加入

obj-$(CONFIG_USB_VIDEO_CLASS) += uvc/

在video的Kconfig中加入

source "drivers/media/video/uvc/Kconfig"

3.编译时选择device driver->usb surport等相关选项（用/搜索UVC）
