BRIO 4K Stream 网络摄像头在 windows-10-pro 机器上没有报告更高的分辨率，而在 windows-10-home 机器上一切正常。

知道如何解决这个问题吗？

到目前为止我尝试了什么：

  1. 从工作机器上获取网络摄像头驱动程序并安装到有问题的机器上
  2. 将 Windows 更新到最新版本
  3. 使用 windows-media-foundation API 列出模式而不是 directshow
  4. 谷歌搜索 logitech brio 的具体问题以及我想到的任何相关问题
  5. 在罗技支持网站上打开的问题
  6. 在网络摄像头之前连接 usb3 集线器
  7. 试过主板上的每个USB端口
  8. 通过 USB-c 到 USB-c 电缆将相机连接到 Geforce RTC 2070 上的 usb3.0 端口

请注意有问题的输出中不存在附加s=1920x1080 fps=60和模式。s=4096x2160 fps=30

谢谢，亚历克斯
