Comment 1 for bug 1323758

Thanks for reporting this bug.

Could you tell us which Ubuntu release you are running? Was 'vlc viewer' a typo, or is that another program you have running beside the vnc viewer?

If you are starting this VM using libvirt, please attach the xml definition for the VM (virsh dumpxml vm-name). If using the command line, please show us the full exact command you are using.

Also please show the result of 'sudo lsusb' after plugging in the usb storage but before passing it through to the guest, then again after passing it through.

Finally please show exactly how you are passing through the usb device.

If these don't show anything obvious then I'll try to reproduce.
