摄像头问题

我用的是2.6.30.4内核，摄像头是中芯微的，插入USB摄像头后，显示的内容是：
[root@EmbedSky /]# usb 1-1: new full speed USB device using s3c2410-ohci and add
ress 4
usb 1-1: New USB device found, idVendor=0ac8, idProduct=3330
usb 1-1: New USB device strings: Mfr=1, Product=2, SerialNumber=0
usb 1-1: Product: Sirius USB2.0 Camera
usb 1-1: Manufacturer: Vimicro Corp.
usb 1-1: configuration #1 chosen from 1 choice
uvcvideo: Found UVC 1.00 device Sirius USB2.0 Camera (0ac8:3330)
input: Sirius USB2.0 Camera as /devices/platform/s3c2410-ohci/usb1/1-1/1-1:1.0/i
nput/input3

接着，我输入WebCam_USB进行测试时，如果出现如下问题：
[root@EmbedSky /]# WebCam_USB
MJPG-streamer [547]: starting application

MJPG-streamer [547]: MJPG Streamer Version.: 2.0

MJPG-streamer [547]: Format............: MJPEG

Unable to set format: Invalid argument

i: init_VideoIn failed

请问这是什么原因，如何解决？

好像不兼容你的这个摄像头哦。读出来的协议不对。你有没有重新配置过内核，添加摄像头的驱动？
