Hi,
I am using latest clone from qemu-kvm git with kernel 2.6.35.7.
Since assigning PCI soundcards, did not yield any usable results, I
assigned a USB headset to a Windows7 VM.
I used the following two command lines to enable the EHCI controller
inside the VM and to assign the device to it:
...
-device usb-ehci,id=ehci \
-device usb-host,vendorid=046d,productid=0a01,bus=ehci.0 \
...
Right after starting the VM I see the following output:
...
Booting from Hard Disk...
Booting from 0000:7c00

"info usb" on the monitor looks like this:
Device 0.1, Port 1, Speed 1.5 Mb/s, Product Microsoft Wireless
Desktop Rece
Device 1.1, Port 1, Speed 480 Mb/s, Product Logitech USB Headset
The sound device shows up under Windows7 and drivers are installed
automatically. Unfortunately it does not work. All the players I tried,
did not even start playing the sound file, although they detected the
DirectSound Device.
When connected to a "natively" running Windows7, the USB headset works
the way it's supposed to.
Any help is greatly appreciated.
Regards
André
