I currently have a logitech MX3000 cordless desktop. Sometimes my computer freezes while playing games, and then when it reboots, the keyboard no longer works, only the mouse does. The receiver is currently connected via usb. However, if I switch usb ports, the keyboard starts working again. But the thing is it has to be a usb port the connector it hasn't used yet. If I connect it to one that the computer froze on, the keyboard doesn't work, even when trying to connect it. I press the connect button on the receiver, and then the connect button on the bottom of the keyboard, and it looks like it connected (the battery light flashes a few times), but it doesn't do anything when I press the keys. Is my keyboard or receiver defective? When the keyboard is connected via a "dead" usb slot, it works to get to bios during booting, but once the windows log on screen comes up, it doesn't work anymore.
Did your keyboard set came with a USB - PS2 plug? Maybe connecting it with that plug. (it is a purple or green plug)
It did come with one, but currently the receiver is connected via usb. Is it possible that my usb drivers need to be updated?
I think you should connect the receiver to the PS2 port using the usb - ps2 connector. (keyboard uses the purple connection). The following plug:
