QEMU/KVM (linux) 客户机中的摄像头直通

我尝试让相机在我的 qemu (Archlinux) 客户机上工作。主机也是Archlinux系统。

下面我展示了我尝试过的命令以及lsusb输出lspci。当我启动访客系统时，我收到关于我已连接的 2 个摄像头的 2 个警告（lenovo 内置、Trust USB 插入）。

我发现一篇文章显然解释了原因这里但我可以弄清楚我到底应该做什么。

导致此问题的原因是虚拟 USB 集线器默认为 USB 1.1 - 如果您在启动 VM 之前将其更改为 USB 2，则相机应该显示正常。但 USB 3+ 设备仍然会出现问题。

- command to start the qemu machine:

$sudo qemu-system-x86_64 -smp 6 -m 4G -enable-kvm -vga std -soundhw ac97\ -usb -device usb-host,hostbus=1,hostaddr=11 -usb -device usb-host,hostbus=3,hostaddr=1 -usb -device usb-host,hostbus=3,hostaddr=2 -usb -device usb-host,hostbus=2,hostaddr=1 -usb -device usb-host,hostbus=1,hostaddr=1 -usb -device usb-host,hostbus=1,hostaddr=2 -usb -device usb-host,hostbus=1,hostaddr=3 -k en-uk -net nic,model=rtl8139 -net user -drive file=qemu-drive,format=raw

- warnings:

qemu-system-x86_64: Warning: speed mismatch trying to attach usb device "Lenovo EasyCamera" (high speed) to bus "usb-bus.0", port "2.6" (full speed)

qemu-system-x86_64: Warning: speed mismatch trying to attach usb device "Trust Webcam" (high speed) to bus "usb-bus.0", port "1" (full speed)
