High definition video switching worked very well but that's where the good news ends. In most cases, this device did not recognize a USB mouse and keyboard for two different brands of such peripherals (some from Logitech and some from Dell). Extensive communication with the technical support on site at the manufacturer did not help; The best they could recommend was a lower-end model, which they claimed offered better USB switching, but couldn't handle the video resolution I needed ie. end up with a KM switch, not a KVM. The device was quickly returned and refunded.
