摄像头驱动的开发问题

我在弄linux下logitechQuickCam Express
摄像头驱动开发.

因是菜鸟,很多东西不懂.特来就教于大虾

我找到一个驱动程序,带源码的,
叫 qce-ga-0.40d

但是按它的说明,编译后执行
脚本quickcam.sh

脚本及执行结果附后.

问题是,编译生成的.o文件mo _quickcam
在lsmod时used计数是0.

而且我也不知道执行报告中usb-ohci.o
uhci.o的错误报告是否有影响?

usb-uhci.o已经成功安装后,其他两个是也要
装上的还是三者有一个就可以的.


另一个问题是,驱动安装成功后,他的设备文件
在那里呢?在/dev/???
因为驱动程序还附了个testquickcam的程序,

它的用法是:
[root@CooCooII testquickcam]# ./testquickcam
 *** Usage ***
./testquickcam DEVICE [ -r | -m | -l ]

 -r reads one frame via read() from the camera
 -m reads one frame via mmap() from the camera
 -l read() loop...good for debugging gain etc


这个DEVICE参数应该怎么给?

脚本文件:
-----------------------
#
# Load the needed modules for the quickcam driver.
#

# you may need these commented out lines if your insmod is too old.
#IS24=`uname -r | grep -c ^2.2`
#
#if [ $IS24 == \"1\" ]
#then
#insmod /lib/modules/2.2.14/misc/videodev.o
#else
#insmod /lib/modules/2.4.0-test10/kernel/drivers/media/video/videodev.o
#fi

#
# Load the modules.

# Video4Linux Support
/sbin/insmod videodev

# USB Core Module
/sbin/insmod usbcore

# USB UHCI/OHCI Controller Modules (new)
/sbin/insmod usb-uhci
/sbin/insmod usb-ohci

# USB UHCI Controller Modules (old)
/sbin/insmod uhci

# that for the sys request key, comment it out if the quickcam works well.
# if you get any erors: use Alt + SysRq + S = Emergency Sync (write everything o
#                       use Alt + SysRq + U = Unmount all HDD\'s
#                       use Alt + SysRq + B = Reboot system immediatly
echo \"1\" > /proc/sys/kernel/sysrq

# quickcam.o is in current directory, after copying in /lib/modules/.../misc,
# use insmod quickcam.
/sbin/insmod mod_quickcam.o

/sbin/lsmod

光这些,好象不能看出什么问题,这样,把你下载的代码发给我看一下:
