Hello, have you checked the read/write permissions of that file/dir for the user this process runs as? you might need to add the user to some additional groups like usb. Please reopen if the problem exists ad add a comment about the file permissions of this dir and `id <user>` of the user you run the emulator as. Thanks, Michael

Ok, since you are running this as root, its no permissions problem, sry.
Just because the init script is started up by a root user doesn't mean the processes it spawns are running as root. Are you using qemu or qemu-kvm for your VM?

From /var/log/libvirt/qemu/vm.log, include the entire command line used to execute qemu-kvm and please include the output of "lsusb".
