[Qemu-devel] [Bug 1643342] Re: not able to passthrough mouse / keyboard

[marius]

** Description changed:

  After upgrading from qemu version 2.6.2 to 2.7.9 I can't boot my vm
  anymore. I get this error:
  
  qemu-system-x86_64: -usbdevice host:046d:c227: could not add USB device
  'host:046d:c227'
  
  This happens with every usb-device I tried. Works in 2.6.2 without any 
errors. (also tried in 2.7.0, same error)
  I use the following script:
  
  qemu-system-x86_64 \
  -enable-kvm \
  -m 16392 \
  -cpu host,kvm=off \
  -smp 4,sockets=1,cores=2,threads=2,maxcpus=4 \
  -usb -usbdevice host:046d:c227 -usbdevice host:046d:c226 \
  -vga none \
  -device vfio-pci,host=01:00.0,multifunction=on \
  -device vfio-pci,host=01:00.1 \
  -drive

 \
  -drive if=pflash,format=raw,file=/tmp/my_vars.fd \
  -device virtio-scsi-pci,id=scsi \
  -drive file=/var/iso/win10.iso,id=isocd,format=raw,if=none -device 
scsi-cd,drive=isocd \
  -drive
