I don't run apparmor. Ubuntu 14.10 host
Have this same issue with USB Host Attachment on Windows and Linux guests. USB Redirection using SPICE is unaffected and works as expected. Libvirt logs show... libusbx: error [_get_usbfs_fd] libusbx couldn't open USB device /dev/bus/usb/003/006: Permission denied libusbx: error [_get_usbfs_fd] libusbx requires write access to USB device nodes. 'chown libvirt-qemu:kvm /dev/bus/usb/003/006' solves the problem and USB Host Attachment now works again. Host dmesg shows... usb 3-13: reset high-speed USB device number 9 using xhci_hcd [ 3346.483029] xhci_hcd 0000:00:14.0: xHCI xhci_drop_endpoint called with disabled ep ffff8807ba9beb40 ...USB device needs to be physically detached and re-attached for host to see again. Tested this with a Sandisk Cruzer Blade 16GB and a Logitech HD C525. -- You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to qemu in Ubuntu. https://bugs.launchpad.net/bugs/1392504 Title: USB Passthrough is not working anymore To manage notifications about this bug go to: https://bugs.launchpad.net/qemu/+bug/1392504/+subscriptions -- Ubuntu-server-bugs mailing list [email protected] Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs
