一段时间后集成的网络摄像头断开连接
当我启动我的ubuntu 12.04时，我可以通过奶酪，Skype等看到我的网络摄像头的输出……但随后它冻结并且在dmesg中它显示断开连接并且它从lsusb消失。 此外，/ dev / video *也消失了。
它以前工作，但由于某种原因现在我有这个问题。 我认为这是一次更新……

我认为网络摄像头实际上已经死了！ 我的Compaq CQ100笔记本上没有任何理由也没碰到我，没有做任何更新或任何事情！ 发现这个线程谷歌搜索同样的问题..
每当我尝试初始化相机时，它旁边的LED会短暂亮起然后熄灭..没有video。 再次尝试应用程序（guvcview）告诉我没有检测到摄像头。 看看dmesg输出，我可以看到，一旦我尝试启动它，相机就会断开连接。
sudo rmmod uvcvideo && sudo modprobe uvcvideo
将/dev/video0带回来但它仍然失败……
