[Qemu-devel] [Bug 685096] [NEW] USB Passthrough not working for Windows 7 guest |
Date: |
Sat, 04 Dec 2010 07:00:46 -0000 |
Public bug reported:
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.
