Ticket #5469 (new defect)

VirtualBox accesses host's USB webcam with VM's virtual USB controller disabled

Reported by: parsifal Owned by:

Version: VirtualBox 3.0.10 Keywords: webcam,usb

Host type: Windows

Description

As per title. Every time I start a VM my webcam is being accessed, as evidenced by a blue LED lighting up on the webcam. The LED stays lit for the complete duration of the VM session and switches off when the VM is powered off.

I am running VirtualBox 3.0.10 on Windows 7 Professional x64. The guest is Ubuntu Linux 9.10 x86 but I do not think that it makes any difference since the webcam's LED lights up immediately after starting the VM, before the guest's code kicks in. The webcam in question is a Hercules/Guillemot Dualpix Exchange:  http://www.hercules.com/us/webcam/bdd/p/21/hercules-dualpix-exchange/

Another piece of info which may be noteworthy is that I noticed the same behavior on and off with some past VirtualBox builds on a (then) Vista x64 host. For example, versions 3.0.8 and 3.0.6 did not exhibit this behavior, but some older builds did.

I am attaching a log from a minimal run of the VM (boot, login screen, poweroff).
