I wondered if there are too many wireless electronic devices in the room and they are interfering with each other and I deactivated almost all wireless devices but the result is still the same. I did all the updates via windows update and the result is the same. I tried different USB ports on the computer case (all front and back) and the result is the same. I disabled the 'turn off this device for power recovery' option on the USB Hub. I downloaded and reinstalled the drivers from Logitech official site but it didn't work. Let me explain some of the methods I tried to solve this problem. The same goes for the keyboard, sometimes it doesn't react even if I press the key many times, and after a few seconds it types all the keys I pressed at the same time. I recently bought the Logitech MK220 Wireless keyboard and mouse set, but then I was very disappointed because, when I move the mouse, it stutters and sometimes it doesn't move at all and it's very frustrating.
