Ok strange one. I have just bought the logitech G15 keyboard, plugged it in and it would not work. tried in all usb's in front and back and they all work with other things. rebooted one more time and it worked no problem.
the rebooted for something unrelated and the keyboard worked but my normal ps2 mouse would not. Had to plug in my old ps2 keyboard to use mouse.
Why would a usb keyboard kill my mouse? Its very strange. Also G15 would not light up and work untill I hit windows. Surley it should work from the off? for BIOS etc.
Any ideas about what I could be missing?
