Thanks for the report. Can you tell me if it works with a Linux guest?
Can you tell me what kind of camera it is (e.g. the descriptors from lsusb -v for the device)? -- You received this bug notification because you are a member of qemu- devel-ml, which is subscribed to QEMU. https://bugs.launchpad.net/bugs/645524 Title: No picture from USB webcam (kvm 0.13-rc1) Status in QEMU: New Bug description: 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. Same problem with different webcams. Same cameras work fine on a native XP install.
