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

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:
0009 0.65470564 vnCDrvUsbControlRequestSetConfiguration,
WdfUsbTargetDeviceSelectConfig single interface failed 0xc00d
0010 0.65472370 vnCDrvUsbIFPrepareHardwareState,
vnCDrvUsbControlRequestSetConfiguration failed: 0xc00d
0011 0.65473646 vnCDrvDevConPrepareHardware,
vnCDrvUsbIFPrepareHardwareState failed 0xc00d
0012 0.65474838 vnCDrvEvtDevicePrepareHardware,
vnCDrvDevConPrepareHardware failed 0xc001
0013 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
