I have ubuntu 11.04 64 bits as a host. I am running VMWare Player 3.1.4 build-385536 and MS Windows XP SP3 as a virtual machine. For some reason, the Vmware Player Windows XP SP3 virtual machine only recognizes the usb Logitech 1080p Webcam Pro C910' as a "sound device" instead of a "video device".
The webcam works out of the box with google voice/video calls (Ubuntu 11.04 64 bits and mozilla firefox), the autofocus works almost instantly. The Ubuntu GNU/Linux skype version doesn't work as well as with Google Voice/Video app, but it works relatively well (the autofocus sometimes doesn't work). The problem starts when I try to use the webcam into a Vmware Player Windows Xp Sp3 virtual machine.
It seems to be a VMware Tools bug.
