I have experienced performance issues with VirtualBox 4.x too and
downgraded to 3.2.14. Perhaps you could give 3.2.14 a try and see how it
works out.

If you get error messages with 3.2.14 I think it is a configuration
issue with the USB driver. I resolved it after consulting the VBox
forums.Iirc they went away after changing permissions on some system files.
