linux UVC and hardware viewer

至于从哪个版本开始内核支持ＵＶＣ，官方的话是“Linux 2.6.26 and newer includes the Linux UVC driver natively.”

１、查看摄像头ID：

[root@151 dev]# lsusb

Bus 002 Device 013: ID 0ac8:3313 Z-Star Microelectronics Corp.

0xc8:3313在ＵＶＣ中支持了。

２、插入摄像头后，就可以在/dev/下查看是否有video设备文件:

[root@151 dev]# ls | grep video

video

video0

其中，video是video0的连接。如果没有再现，可能ＵＶＣ没有配置到内核中，重新配置就可以了

（大致在Device DriversàMultimedia devicesàVideo capture adaptersàV4L USB devices下面）。如果内核配置了，

还是不出现，可以使用modprobe uvcvideo来加载该模块。

３、先看看摄像头的相关信息：

lshal | grep Cam

出现：

info.product = 'Vega USB 2.0 Camera.' (string)

usb_device.product = 'Vega USB 2.0 Camera.' (string)

usb.interface.description = 'Vega USB 2.0 Camera.' (string)

info.product = 'Vega USB 2.0 Camera.' (string)

input.product = 'Vega USB 2.0 Camera.' (string)

info.product = 'Vega USB 2.0 Camera.' (string)

对ＵＳＢ有研究的，就很熟悉这些字段。

再看一下系统能不能识别出摄像头：

[root@151 log]# dmesg | grep Cam

uvcvideo: Found UVC 1.00 device Vega USB 2.0 Camera. (0ac8:3313)

input: Vega USB 2.0 Camera. as /class/input/input6

uvcvideo: Found UVC 1.00 device Vega USB 2.0 Camera. (0ac8:3313)

[root@151 ~]# dmesg | grep video
