[Qemu-devel] [Bug 685096] Re: USB Passthrough not working for Windows 7 guest

[Jens Frederich]

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:
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

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.
