Review: Works with a little bit of adjustment. - Purchased this knowing it wasn’t 4k video or USB 3. Connected everything up and it didn’t work. Instructions were simple and should have worked. Things were not set at manufacturers defaults and had to adjust until it worked. There wasn’t enough info to figure out what each switch setting did, or what setting did what as far as what plugged into it. Now that it is working, I am highly recommending it.
Review: Great for video, not for USB. - The video and audio portion works great, although one of the dip switches was in the wrong position when it arrived and the documentation is extremely lacking. Evidently all four dip switches should be in the left position. When it arrived with one of the dip switches in the right position the video worked fine but there was no HDMI audio. My complaint is the lack of USB support. I know it is listed as a KVM but the seller indicated in the Q&A that the device meets full USB 2.0 specs. It will not work with anything I have tried other than a keyboard and mouse. It works just fine with a wireless Logitech keyboard and a wireless Razer mouse if they are plugged directly into the receiver. It also does not work with an Xbox One USB dongle or with a Bluetooth dongle. I also does not work with a powered or unpowered USB 2.0 hub. All of the components I tested work when connected directly to my computer via a USB 2.0 port.
