VirtualBox: No USB?

[david-8uUts6sDVDvs2Lz0fTdYFQ at public.gmane.org (David Kramer)]

Backstory: I have an ancient Thinkpad T42 running Windows XP.  I have
only two uses for Window; backing up/sycning my iPhone, and VPNing into
work.  The Thinkpad's Windows install is broken, and it BSOD's seconds
after booting.  I may or may not reinstall Windows on it.

I found an XP image I made in VirtualBox a while ago on an external USB
hard drive.  I installed VirtualBox on my main laptop (Dell D830
Centrino dual core duo).  I tried it for VPNing into work, and that
worked pretty well.  However, I can't find any way of seeing USB devices
(like my iPhone) in the VM.

I see all sorts of tutorials online that refer to there being a
button/icon that lists USB devices that I can choose to take control of,
but I don't see one.

This is what I have installed:
$ dpkg-query -l '*virtualbox*' | grep ii
ii  virtualbox-guest-additions
   3.2.8-1~lucid1
   guest additions iso image for VirtualBox
ii  virtualbox-ose
   3.2.8-dfsg-2ubuntu1~lucid1
   x86 virtualization solution - base binaries
ii  virtualbox-ose-dkms
   3.2.8-dfsg-2ubuntu1~lucid1 x86
   virtualization solution - kernel module
ii  virtualbox-ose-qt
   3.2.8-dfsg-2ubuntu1~lucid1
   x86 virtualization solution - Qt based user

PS I'm willing to go with a different VM solution.  I just chose
VirtualBox because I already had a VirtualBox VM image and most of the
articles I found on using a Windows VM to talk to an iPhone used VirtualBox.
