它对奶酪不起作用。
从lsusb
:
Bus 003 Device 002: ID 045e:075d Microsoft Corp. LifeCam Cinema
从dmesg
,重新连接摄像机时:
[ 2098.426935] usb 3-1: USB disconnect, device number 2

打开奶酪时dmesg
:
[ 2283.440820] xhci_hcd 0000:04:00.0: ERROR: unexpected command completion code 0x11.
[ 2283.440830] usb 3-1: Not enough bandwidth for altsetting 6
在奶酪上我看到以下错误(是的,我知道,不是很具说明性):
There was an error playing video from the webcam
我读到问题可能是网络摄像头请求的带宽太多,但说实话,我对 USB 和摄像头的了解为零,而且我找不到任何解决方法。
相机上也有麦克风。不确定是否相关。只有相机工作就足够了,但我当然希望麦克风也能工作。
答案1
我发现我的电脑有两个 USB 集线器。我确保一个集线器的所有端口都用于其他用途,而第二个集线器只连接了摄像头。它解决了这个问题,但不确定是否有更好的解决方案。
答案2
cheese 最初不工作。但安装 guvcview 之后,cheese 工作正常。
sudo apt-get 安装 guvcview
