Package: qemu-system Version: 1:6.2+dfsg-2 Severity: important When attaching a usb devices on either xhci or ehci emulated controllers, they using `usb-host` option, they do not get detected by the guest operating system, whether guest is a Linux or Windows system. Other types of emulated usb interfaces work (I tested `usb-tablet` and `usb-audio`).
The commandline I use is: qemu-system-x86_64 -m 4096 \ -enable-kvm -cpu host -smp cores=2 \ -rtc base=localtime,clock=host \ -drive driver=raw,file=${WINDOWS10IMG},if=virtio \ -net nic,model=virtio-net-pci \ -net user,hostfwd=tcp:127.0.0.1:13389-:3389 \ -vga virtio \ -device qemu-xhci,id=xhci \ -device usb-host,bus=xhci.0,vendorid=0x046d,productid=0x0825,id=cam0 \ -device usb-tablet I have tested with 4 different devices, namely: - Logitech C270 Webcam (046d:0825) - USB Flash Disk - Bluetooth module (internal, 8087:07dc) - Ericsson N5321 gw modem (internal, 0bdb:193e) The webcam does show up as an audio interface if I use `usb-audio` option to add it instead of `usb-host`. It is not usable as `usb-audio` does not support microphones, but it shows that the `usb-audio` interface in qemu does work for USB devices. All the devices show up in qemu monitor's `info usbhost` command output, and after adding them with `usb-host`, the monitor shows them, even though they are completely inaccessible to the guest. -- System Information: Debian Release: bookworm/sid APT prefers unstable APT policy: (500, 'unstable'), (1, 'experimental') Architecture: amd64 (x86_64) Foreign Architectures: i386 Kernel: Linux 5.15.0-3-amd64 (SMP w/4 CPU threads) Kernel taint flags: TAINT_OOT_MODULE, TAINT_UNSIGNED_MODULE Locale: LANG=en_US.UTF-8, LC_CTYPE=en_US.UTF-8 (charmap=UTF-8), LANGUAGE=en_US:en Shell: /bin/sh linked to /usr/bin/dash Init: systemd (via /run/systemd/system) LSM: AppArmor: enabled Versions of packages qemu-system depends on: ii qemu-system-arm 1:6.2+dfsg-2 ii qemu-system-mips 1:6.2+dfsg-2 ii qemu-system-misc 1:6.2+dfsg-2 ii qemu-system-ppc 1:6.2+dfsg-2 ii qemu-system-sparc 1:6.2+dfsg-2 ii qemu-system-x86 1:6.2+dfsg-2 qemu-system recommends no packages. qemu-system suggests no packages. -- no debconf information
