USB pass-through didn't work on windows 8. I try to use "virt-mamanger", and set USB interface to USB 2.0. Then everything works well. The default one would be USB 1.0. I don't know how to transform virt-manager's configuration to QEMU's command line arguments. Hope this help. -- = You received this bug notification because you are a member of qemu- devel-ml, which is subscribed to QEMU. https://bugs.launchpad.net/bugs/685096 Title: USB Passthrough not working for Windows 7 guest Status in QEMU: Confirmed Status in =E2=80=9Cqemu-kvm=E2=80=9D package in Ubuntu: Confirmed Bug description: USB Passthrough from host to guest is not working for a 32-bit Windows 7 guest, while it works perfectly for a 32-bit Windows XP guest. The device appears in the device manager of Windows 7, but with "Error code 10: device cannot start". I have tried this with numerous USB thumbdrives and a USB wireless NIC, all with the same result. The device name and functionality is recognized, so at least some USB negotiation is taking place. I am trying this with the latest git-pull of QEMU-KVM. The command line to launch qemu-kvm for win7 is: sudo /home/user/local_install/bin/qemu-system-x86_64 -cpu core2duo -m 102= 4 -smp 2 -vga std -hda ./disk_images/win7.qcow -vnc :1 -boot c -usb -usbdev= ice tablet -usbdevice host:0781:5150 The command line to launch qemu-kvm for winxp is: sudo /home/user/local_install/bin/qemu-system-x86_64 -cpu core2duo -m 102= 4 -smp 2 -usb -vga std -hda ./winxpsp3.qcow -vnc :0 -boot c -usbdevice tabl= et -usbdevice host:0781:5150 Any help is appreciated.
