Til qemu version 1.6.2 USB passthrough works perfectly, but starting with qemu 2.0.0 passthrough stop working. I can still add the usb device but when I start the guest following message appears: "unable to execute QEMU command 'device_add': 'usb-host' is not a valid device model name" Then the guest will not start. I try it with different usb devices (iphone, stick, hdd), always the same error. Are there any news / hints about this ? Regards Martin Be sure to add the -usb option. What is your command line?

So you should build qemu with --enable-libusb, then you can use usb pass-through capacity. BTW, Gerd, should we enable libusb by default now? Thanks.
