USB摄像头驱动问题：Init v4L2 failed !! exit fatal

[handersonhlj]

新买了一个摄像头，是SGS320FL + OV7670的。将它连接到linux-2.6.30.4内核的板子上，驱动不了；但是我之前的ZC301能够驱动起来。是不是我的驱动有问题呢？我只是将OV7670的驱动加进去了，但是摄像头的主控芯片驱动没找到。错误如下：
Unable to set format: Invalid argument
Init v4L2 failed !! exit fatal
i: init_VideoIn failed

我在内核里将gspca里的驱动，都加上了，编译后，还是不行。

Unable to set format: 22.
格式不对。
可以查询摄像头支持的格式，再进行设置。格式如YUYV、MJPEG，等等。更详细的可以参考V4L2的手册。

你的摄像头是基于UVC的，不是gspca的，我也只知道这些了。
