IGHOR Posted May 16, 2020 Posted May 16, 2020 (edited) Hello. I'm trying to connect USB web camera to my VM, and it does work, but looks like very slow since image lost every few seconds. In the VM I can find that USB device and it says it is connected to USB 2.0, but it looks like speed of USB 1.1 I think if it would be possible to enable IOMMU it would fix problem, but I hope there is some another way. In the VM settings I can find USB Devices: Logitech Webcam C170 (046d:082b). By enabling its checkbox I attach the web camera. Other devices that don't need a high speed works fine this way. Here is my System Devices info and I'm trying to passthrough Logitech, Inc. Webcam C170. Is there any additional QEMU commands that would help me to fix performance issue?
