use*_*557 5 usb cheese drivers uvc guvcview
我在亚马逊上买了一个猫足 5mp USB 显微镜（在查看它在 Linux 上工作的评论之后）。遗憾的是，当我在 Lubuntu 16.04 上连接它时，它在 guvcview 或 cheese 中不起作用。
我做了一些调查。我在下面展示了相关部分：
ls /dev | grep video
video0
video1
显微镜在视频 1 上，罗技网络摄像头在视频 0 上。未连接显微镜时网络摄像头工作，但连接显微镜时guvcview和cheese无法从中检索视频：

我终于解决了。经过大量时间的测试和理论分析，我得出的结论是，问题与驱动程序或操作系统版本无关。似乎只有一台特定的机器出现了问题。这表明存在硬件问题。一次偶然的机会，我偶然发现了一篇关于 ASMedia USB3 设备与 Kinect2 的所有问题的文章。我的主板（Asus X99 Deluxe II）的规格显示它使用 ASMedia for USB3，但显然不是 USB2。我将网络摄像头和显微镜切换到 USB2 端口，此后就没有出现过问题。
非常感谢克里斯托弗·艾夫斯 (Kristopher Ives)，他在这方面付出了很多努力来帮助我。
结论 如果您在使用 UVC 设备时遇到问题并且拥有 ASMedia USB3，请尝试 USB2 端口。ASMedia USB 也很糟糕！
