  1. Start the VM
  2. Add Hardware->USB Host Device
  3. Choose the device you want to assign from the list, like: 009:002 SanDisk Extreme
  4. Click Finish
  5. Verify that the guest shows up in 'lsusb' output in the guest.
  6. Verify the device's functionality in the guest (this will be device specific)
  7. Select the device in virt-manager, and click 'Remove'.
  8. Verify the device again appears in the host, and is functional on the host.

Using virt-xml

  • Find the device you want to attach in the output of lsusb, copy the ID string, something like 0781:5406
  • Attach the device to running VM 'test-day-vm' using virt-xml:
 sudo virt-xml test-day-vm --update --add-device --host-device 0781:5406
  • Verify the device is usable in the VM
  • Remove the device from the running VM 'test-day-vm':
 sudo virt-xml test-day-vm --update --remove-device --host-device 0781:5406
  • Verify the device is visible and functioning on the host machine

Expected Results

No obvious errors occur.
