USB摄像头是ANC的，插在mini2440开发板上超级终端显示如下信息 [root@FriendlyARM /]# usb 1-1: new full speed USB device using s3c2410-ohci and

在触摸屏上测试USB摄像头能成功，但是在Fedora9下测试不能成功，
我是参照这个做的http://blog.chinaunix.net/u3/103472/showart_2084142.html
下面是我在Fedora9下的操作信息：

是不是驱动的问题，或者说 spcaview 是不是基于V4l1的，驱动是基于V4l2的等，这些问题我搞不清楚。怎么做才能在Fedora9下用这个USB摄像头成功采集图像，请大家帮个忙，非常感谢。
