Hi, The problem actually is that you need to add '-usb' to your kvm command line. If you do 'info usb', you'll see 'USB support not enabled'.
Without the '-usb' command line option, I get the same results as you do. With the '-usb' option, I get permission denied. Finally, running that as root, it succeeds for me. ** Changed in: qemu-kvm (Ubuntu) Status: Incomplete => Invalid -- usb_add not working in qemu monitor https://bugs.launchpad.net/bugs/576086 You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to qemu-kvm in ubuntu. -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs
