Browsing the discussion forums, I found that this has problems connecting a keyboard and mouse to a USB 3.0 port. After I fixed the problem with my only 2.0 ports, this product worked fine for maybe a week. After that, the monitors switched, but the keyboard and mouse didn't. Shortly thereafter, the HDMI switch stopped working. Look - I can't rule out mistakes on my part with my USB 2.0 ports. But the HDMI switch stopped working? I see many other users have more experience than me. Maybe I have a bad block? Anyway, I went back to a more expensive 4-port KVM switch.
