由于linux-2.6.24.4/drivers/usb 目录下没有media目录，故移植步骤如下：

a)在linux-2.6.24.4/drivers/usb 目录下新建media目录，将gspcav1-20071224.tar.gz copy到media下解压。为了使media编译进内核，需修改linux-2.6.24.4/drivers/usb目录下的Kconfig、Makefile文件。

[root@localhost yaffs2]# cd ../linux-2.6.24.4/drivers/usb/

[root@localhost usb]# pwd

/root/2410-s/linux-2.6.24.4/drivers/usb

[root@localhost usb]# mkdir media

[root@localhost usb]# cd media/

[root@localhost media]# cp /mnt/hgfs/arm/gspcav1-20071224.tar.gz ./

[root@localhost media]# mv gspcav1-20071224 gspca

[root@localhost media]# cd ..

[root@localhost usb]# pwd

/root/2410-s/linux-2.6.24.4/drivers/usb

[root@localhost usb]# vi Kconfig

添加 source "drivers/usb/media/Kconfig"

[root@localhost usb]# vi Makefile

添加 obj-$(CONFIG_USB_SPCA5XX) += media/

b)为添加gspcav1-20071224 编译选项，在media下新建Kconfig、Makefile文件。

[root@localhost usb]# cd media/

[root@localhost media]# pwd

/root/2410-s/linux-2.6.24.4/drivers/usb/media

[root@localhost media]# vi Kconfig

#
# USB Multimedia device configuration
#
comment "USB Multimedia devices"
        depends on USB

config USB_SPCA5XX
        tristate "USB SPCA5XX Sunplus/Vimicro/Sonix jpeg Cameras"
        depends on USB && VIDEO_DEV
        ---help---
          Say Y or M here if you want to use one of these webcams:

          The built-in microphone is enabled by selecting USB Audio support.

          This driver uses the Video For Linux API. You must say Y or M to
          "Video For Linux" (under Character Devices) to use this driver.
          Information on this API and pointers to "v4l" programs may be found
          at <file:Documentation/video4linux/API.html>.

          To compile this driver as a module, choose M here: the
          module will be called spca5xx.

 

 [root@localhost media]# vi Makefile

# Makefile for USB Media drivers

obj-$(CONFIG_USB_SPCA5XX) += gspca/
