Thanks Michal,
so at sounds like at least that file should be distributed with the qemu
package. I don't know the best place for that, or how cleanly we can
integrate it to make it easiest on the end-user...

Title:
USB Passthrough not working for Windows 7 guest
Status in QEMU:
Confirmed
Status in “qemu-kvm” package in Ubuntu:
Incomplete
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.
