What OS is your host system? Did you connect your USB device every time to your VM?

host win7
guest ubuntu 14.04

Did you connect your USB device every time to your VM?
I don't remember whether it's first time I've connected on this machine or not.
But I know that on another machine host fedora guest fedora, it runs like a charm (the single requirement is to run virtualbox as root from host)

If you connect a USB device after the VM ist booted up, you may have to connect the device via the USB menu down on the VirtualBox window.

You have to add an USB filter. Machine / Settings / Ports / USB / Add filter.

To disconnect the USB from Ubuntu, use the small icon in the lower right (next to HD activity and network activity icons).

You may have to install the VirtualBox Additions within Ubuntu (although Ubuntu normally has tools ready, they may not always be installed or, they could be outdated versions). Also, when you want to use any USB device inside a VM, you first have to make sure it isn't being used by the host OS. Any USB device can only be in use by any one device at the same time. Once the host OS isn't using it, it should become available for attaching inside the VM.
