Hi Serge, for your information. I sent a mail to the devel mailing list. See below.
I've tried to passthrough special Vector automotive usb in house devices. Look here: http://vector.com/vi_vn1600_en.html. What do you mean with "what commands you've tried"? I've tried three QEMU versions: 1. Ubuntu 13.04 64-bit prebuild qemu-kvm package (qemu 1.4.0) 2. Ubuntu 13.10 64-bit prebuild qemu-kvm package (qemu 1.5.0) 3. Hand builded QEMU 1.6.1 with standard configure call $ ./configure --prefix=/opt/kvm && make -j Next, I want to build qemu from git? I use virt-manager or virsh to start/stop my guest. The QEMU command line is: qemu-system-x86_64 -machine accel=kvm:tcg -name VRTP1_win -S -M pc- i440fx-1.4 -cpu SandyBridge -m 3072 -smp 2,sockets=1,cores=2,threads=1 -uuid 8ee5add7-f1a9-d697-9c18-2c1b4967c00e -no-user-config -nodefaults -chardev socket,id=charmonitor,path=/var/lib/libvirt/qemu/VRTP1_win.monitor,server,nowait -mon chardev=charmonitor,id=monitor,mode=control -rtc base=localtime -no-shutdown -device piix3-usb-uhci,id=usb,bus=pci.0,addr=0x1.0x2 -device ahci,id=ahci0,bus=pci.0,addr=0x6 -drive file=/var/lib/libvirt/images/VN8912_Development_0.9.2.bin,if=none,id =drive-sata0-0-0,format=raw -device ide-hd,bus=ahci0.0,drive=drive- sata0-0-0,id=sata0-0-0,bootindex=1 -netdev tap,fd=27,id=hostnet0,vhost=on,vhostfd=28 -device virtio-net- pci,netdev=hostnet0,id=net0,mac=52:54:00:71:f5:45,bus=pci.0,addr=0x3 -chardev pty,id=charserial0 -device isa- serial,chardev=charserial0,id=serial0 -device usb-tablet,id=input0 -vnc 127.0.0.1:0 -vga std -device intel-hda,id=sound0,bus=pci.0,addr=0x4 -device hda-duplex,id=sound0-codec0,bus=sound0.0,cad=0 -device usb- host,hostbus=3,hostaddr=18,id=hostdev0 -device virtio-balloon- pci,id=balloon0,bus=pci.0,addr=0x5 Mail to devel list: Hi all, we're currently evaluating different RTOS systems (Windows CE, Intime, RTX, etc.). One system is Linux RT + KVM/QEMU with a Windows 7 guest. Up to now all works fine, Linux RT has good latency and KVM/Qemu setup was easy. But one QEMU bug breaks my measurement setup and evaluation. I've some usb devices for the Windows 7 guest. I configure them as USB passthrough. The devices appears in the device manager of Windows 7, but with "Error code 10": device cannot start". The Windows driver fails on USB set configuration. The driver creates a IRP and send it via IOCTRL to lower layer. The IOCTRL fails with invalid parameter. driver log: 00000009 0.65470564 vnCDrvUsbControlRequestSetConfiguration, WdfUsbTargetDeviceSelectConfig single interface failed 0xc000000d 00000010 0.65472370 vnCDrvUsbIFPrepareHardwareState, vnCDrvUsbControlRequestSetConfiguration failed: 0xc000000d 00000011 0.65473646 vnCDrvDevConPrepareHardware, vnCDrvUsbIFPrepareHardwareState failed 0xc000000d 00000012 0.65474838 vnCDrvEvtDevicePrepareHardware, vnCDrvDevConPrepareHardware failed 0xc0000001 00000013 0.6547 This bug breaks my latency measurement setup and Linux RT is out of the evaluationg race. Windows CE should not win :-), it there anyway workaround or hack to fix the issue? My setup: Ubuntu 64-bit Windows 7 Embedded Guest Linux Kernel: 3.10.10-rt7 QEMU: 1.4.0, 1.6.1 thanks, Jens -- 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 “qemu-kvm” 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 1024 -smp 2 -vga std -hda ./disk_images/win7.qcow -vnc :1 -boot c -usb -usbdevice 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 1024 -smp 2 -usb -vga std -hda ./winxpsp3.qcow -vnc :0 -boot c -usbdevice tablet -usbdevice host:0781:5150 Any help is appreciated.
