我的笔记本电脑无法再检测到我的网络摄像头，所以我无法拍照或从网络摄像头看到自己。
我一直在使用 Ubuntu 16.04 LTS，一切都很顺利...，直到我决定安装 17.04。安装 17.04 后，我遇到了这个问题。
在 16.04 中，我无需安装网络摄像头驱动程序或类似的东西。网络摄像头工作正常。
在 17.04 中，当我尝试访问 Cheese 中的网络摄像头时，它只显示一个黑色窗口，上面写着：
未找到设备
见下文：
所以我决定安装网络摄像头驱动程序。
我搜索过，但找不到任何有用的代码来安装驱动程序......
我的笔记本电脑：MSI GE62 6QD-C
我不知道该如何解决这个问题...

输出表明两个驱动程序都处于活动状态。
我尝试了所有这些命令来激活：
modprobe rtsx_usb
modprobe usbhid
然后我也尝试使用 sudo：
sudo modprobe rtsx_usb
sudo modprobe usbhid
什么都没发生！
