Hi, Sorry for the delay. I just tested this evening the workaround you suggest. And I can confirm that, indeed, adding a udev rules to change to ownership of the usb device file is enough for qemu lauched by libvirt to work. I manually added the rule for my USB printer. I do not know how this can be made generic. But at least, I can now use the latest qemu package for my VM.
