I am running Maverick on my machine and I have Lexmark X6675 connected to the system via USB. I also have VirtualBox 4.1 running Windows Vista on the system. And I have a very interesting situation with Printing.
If I have VirtualBox running with USB device that is my printer enabled to VirtualBox I am unable to print from Ubuntu. I have to shutdown VirtualBox (I haven't tested but disabling the USB access probably does the same, I'll have to check) and then I can print from Ubuntu.
Is this normal behavior? Is there a way to configure either VirtualBox or Ubuntu or both so that they can gracefully share the printer?
