我的系统是ubuntu8.04，插上摄像头以后没有反应，使用lsusb查看设备结果如下：
Bus 005 Device 001: ID 0000:0000
Bus 003 Device 001: ID 0000:0000
Bus 004 Device 001: ID 0000:0000
Bus 002 Device 005: ID 1c4f:3000
Bus 002 Device 001: ID 0000:0000
Bus 001 Device 001: ID 0000:0000
1c4f:3000就是我的摄像头了，貌似没有识别出来。
用dmesg查看得到信息：

尝试安装了linux-uvc driver似乎也没用，不知该怎么解决，请大家帮帮忙，谢谢了。
