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

---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
