This KVM switch has two USB 3 hub ports. 1 front and 1 rear. I connected the rear USB 3 port to a ViewSonic XG monitor using a hub extension cable. I have a camera, headset and programmable keyboard connected to an XG monitor as an extension to a USB KVM hub. Programmable keyboards with dual interface cables will not work with this KVM, but so far it seems that programmable mice will work, so I used a monitor to pair with the keyboard. The front USB hub works well with removable drives. For those who only have an HDMI graphics card, you'll need a USB-powered HDMI-to-Game port adapter on the PC side, which is easy to find.
