    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

    usb 2-7: Product: Vega USB 2.0 Camera.

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

    input: Vega USB 2.0 Camera. as /class/input/input7

    usb 2-7: Product: Vega USB 2.0 Camera.

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

    input: Vega USB 2.0 Camera. as /class/input/input8

    usb 2-7: Product: Vega USB 2.0 Camera.

    [root@151 ~]# dmesg | grep video

    You can install HAL from the PPA.

    sudo add-apt-repository ppa:mjblenner/ppa-hal
    sudo apt-get update
    sudo apt-get install hal
