我以前提出過這個問題。但我試圖再次發佈之前做更多的研究。這裏的問題：VMWare上的攝像頭可見但「無框架」Ubuntu客戶端
我已經安裝Ubuntu 12.04在VMWare 6.0與Windows 7作爲主機。 我正嘗試在Ubuntu上訪問我的攝像頭，但一段時間後我只成功一次。
的結果的lsusb是：
[email protected]:~$ lsusb
Bus 001 Device 002: ID 046d:082d Logitech, Inc.
Bus 002 Device 002: ID 0e0f:0003 VMware, Inc. Virtual Mouse
Bus 002 Device 003: ID 0e0f:0002 VMware, Inc. Virtual USB Hub
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 002 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
但是當我運行像 「奶酪」 或 「qv4l2」 應用程序，我得到這樣的錯誤：
（qv4l2）
libv4l2: error turning on stream: Broken pipe
Start Capture: Broken pipe
VIDIOC_STREAMON: Resource temporarily unavailable

我甚至曾嘗試LD_PRELOAD溶液以及相同的結果。 希望對此有所瞭解。
我試圖消除uvcvideo模塊，然後重新安裝。第一次工作，但沒有成功之後:( – harsh
我嘗試了相同的設置在朋友的計算機上。我禁用VMWare USB自動連接。每次沒有看到幀，我手動斷開連接並從設置連接攝像頭，它的工作。這在我的電腦上不起作用。 – harsh
