救急,VC0342摄像头使用问题,UVC驱动问题吗?
新买的摄像头VC0342PLVCE,不知道出了什么问题,在电脑上工作正常。但是在ARM11(mini6410)开发板上使用,不能够正常读出设备。开发板主控芯片:S3C6410,移植的系统内核版本:2.6.36(额外测试了2.6.38版本)。但是用其他厂家的同种类型的主控芯片摄像头工作正常(VC0342+MI2010和VC0342+MI1320)。现在要统一使用新的摄像头,但是新的摄像头却出现了这种情况,不知道什么原因,希望大家帮帮忙。情况描述如下:
插上USB摄像头后打印信息:

插上摄像头后没有在/dev目录下自动出现设备节点video2.
通过命令新建mknod /dev/video0 c 81 0也不能够使用
找了很多的资料都不知道怎么办,没有解决问题的。
