I'm trying to connect an NXT Robot to a windows XP guest in Virtualbox, I have installed virtualbox's Extension Pack. Not a single usb device shows up in virtual box, yet lsusb shows they are all connected to my host.

```
william@ubuntu-laptop:~$ lsusb

Bus 002 Device 004: ID 049f:0051 Compaq Computer Corp. KU-0133 Easy Access Interner Keyboard

As you can see, my robot is connected on the first usb, yet nothing shows in Vbox, not even mouse and keyboard, is vbox hiding them by default since they not a storage device? (I have not tried connecting a usb key) I need to way to force Vbox to forward control of the device through the guest, where I can connect it to the RobotC IDE.

I installed Vbox through the software centre. It is version 4.3.26 (Latest, only installed it today)
