I only use 2 of the 4 ports on this KVM with a wireless mouse and keyboard. I had no issues with the HDMI ports, but the 2 USB ports on the back were very unreliable for both wired and wireless keyboard and mouse. My wireless mouse and keyboard didn't work reliably with any of the four USB ports. I had to constantly plug and unplug to get it working but then stop again during use. The only setup that seems to work for me is a wired keyboard on the back (USB2) and a wired mouse on the front (USB4). I tried to connect a wired mouse to the rear USB port (USB1), but it also didn't work reliably when I switched the input. i need a product
