USB webcam detected in KVM, but doesn't work
- by Gene Vincent
I have installed XP in a virtual machine running on Linux with QEMU/KVM (qemu-kvm-0.11.0-4.5.2).
I export my Linux webcam to KVM using the switches "-usb -usbdevice host:046d:0929". The XP guest sees the webcam and the drivers install, but the camera only shows a black image. When I open the camera in Windows Explorer, it says "0 images" and a black image, while on a real XP, it says "1 image" and shows the video from the camera.
I tried the same with a different webcam, but the result is the same.
Any ideas what might be wrong or how I could debug this ?
