[root@localhost ~]# lshal |grep usb
然后就找 ZC0303字样的设备 ，那一大段都要仔细的看;
也可以这样的方法;
[root@localhost ~]# lshal -s |grep usbusb_device_0_0_0000_00_1d_0usb_device_0_0_0000_00_1d_0_if0usb_device_4fc_3_noserialusb_device_4fc_3_noserial_if0usb_

我们看到带有video4linux字样的，他的设备号是 usb_device_ac8_303b_noserial_video4linux字样的，在其前面还有几个差不多的编号的设备。比如 usb_device_ac8_303b_noserial。我们就先查这个设备，大多数这样的一组相似的设备号，查第一个就能知道是什么设备。于是用。。

在Gnome桌面环境下，还用hal-gnome软件包工具可用;您可以通过下面的方式来安装此软件包
[root@localhost ~]# yum install hal-gnome
然后运行hal-device-manager工具;
[root@localhost ~]# hal-device-manager
点鼠标查看摄像头的详细信息还是没有问题吧。
