请问cubieboard2怎样点亮USB摄像头？

wb4916

USB摄像头已经在WIN7 64位的系统上面确认是好的！（AMCAP.EXE可以点亮，驱动通过驱动人生安装的）

现代（HYUNDAI）HYC-W800 免驱 网络高清摄像头 外置麦克风 蓝色
国际品牌，5G高清镀膜镜头，外置高保真麦克风，内置4盏LED夜视灯，超强防盗防滑底座设计!




系统：android4.2.2
2)在百度云下载源码压缩包:

cubieboard2使用ov7670模块

按照这个帖子，点亮了OV7670。

DVK522的扩展板主页上说明：USB CAMERA会被配置成为/dev/video0的
CSI CAMERA(OV7670)        VIDEO1
USB CAMERA        VIDEO0




插入USB摄像头，在穿口中敲入：dmesg，可以看见这个。
