I have an adapter for connecting PS/2 keyboard and mouse to USB port on a notebook -- TRENDNET USB A (m) — PS/2 (see image below).
Unfortunately, it doesn't work with my ASUS notebook (neither plugged in USB 2.0, nor USB 3.0). But it does work with my desktop computer, which is already has PS/2 sockets.
Can I fix the problem somehow, maybe installing a driver? (Which one then?)
