I have a USB wired keyboard and wireless Mouse with a USB receiver. Almost every USB port I have is used, so I wanted to relieve the ports of some burden by transfering my keyboard and mouse to PS/2 ports. I have ASUS PRIME A320M-K motherboard. I recently purchased cheap USB [female] to PS/2 [male] adapters, only to find out that they're of no use. In the logs, I have seen this:
i8042: PNP: No PS/2 controller found
So, I reckon there is no circuit inside those adapters that will actually convert USB signals to PS/2 signals. By the way, I'm not sure what they are good for.
I'm looking for recommendations regarding hardware that will solve the problem by making me able to utilize my PS/2 ports properly, thus freeing up the USB ports.
I've searched online, and the only thing I could find is rather expensive for such a simple device (~$150).
