Logitech G9 + Windows 7

Hi All,
I have a Logitech G9 mouse that Windows 7 can't see.
It worked fine on xp and vista, and I have installed the latest setpoint510_g9,
which istalls fine. But it doesn't detect any Logitech hardware.

i've tried a few different usb ports,
but the lights on the mouse don't even light up -and it certainly wont move the cursor!

anyone else had this problem?
