One quick note. When using my USB mouse through this adapter, if I click on a scroll bar and drag downwards a bit, then stop with the mouse held down, the mouse will stop moving until I let go of the button. This does not happen with the normal 2 button mouse.
Also, my Logitech 'Performance MX' wireless mouse works fine through the Spider card, but not through the USB to 9pin adapter. Which probably is just because it doesn't supply enough power. It's 5v 100ma for the 'Boing Ball' mouse.
