Vista not seeing my keyboard/controller

Hello I just built a new computer and I have a G-15 gaming keyboard from
logitech and the wireless xbox 360 controller from M$. I am using vista 32
bit home premium and they were both working fine now after a few vista
updates and other changes Vista can no longer "see" them. I can still use
the keyboard but vista does not recognize the G keys or the LCD screen and
the G-15 profiler crashes when I try to load it. It can no longer see my
xbox controller at all, if I goto control panel>game controllers>preferred
device vista no longer has the 360 controller as an option it just says
<none> I have strong reason to believe that recent vista updates have caused
this problem because I installed both peieces of hardware on another vista
box that had never been updated and they are working fine together (initially
I had thought they were just conflicting with each other) Is this a known
issue? What steps can I take to try and fix this?
