I am able to use my internal bluetooth chip on Ubuntu (obvious). But I can't use it in a virtual machine(Windows xp) installed with Virtualbox. I also have a USB bluetooth dongle. But the problem is that my virtual machine doesn't show any 'found new hardware' or similar thing in it's task bar. FYI I have installed guest additions too, but I am still unable to get any USB device working with the virtual machine.
How can I use bluetooth in the virtual windows xp machine (with internal chip/ USB dongle)?
