StarTech 2-Port USB HDMI KVM Switch with Audio and USB 2.0 Hub

Let me start off by saying that I absolutely love this KVM and I adore the quality of the support that Startech provides. I didn't actually contact Startech support on this particular issue since the product details page clearly states that the unit doesn't support USB wireless receivers like those provided by Logitech UNIFYING receiver line of products. That being said I allowed myself to get carried away with reviews on Amazons site and I saw that other people used their Logitech Unifying receivers with no issues. Let me say that with both an older and newer Logitech Unifying receiver I did experience issues with one half of the two devices that I attached to this KVM. On my Lenovo Laptop I had no issues and the L.U.R (unifying receiver) worked like a champ but when I toggled the KVM to go back to my Dell Desktop I had an inordinate amount of lag and loss of cursor and keyboard responsiveness to the point of it being unusable. So if you are wanting to use this device as a your KVM my advice is to adhere to the technical warnings and even ignore my review and others and just be prepared to have a bad experience with your USB based wireless receivers. I do not hold Startech to blame on this issue since they were clear up front and I failed to heed the warning. I highly endorse this KVM but please be prepared to use a wired USB mouse and keyboard with this KVM. Cross posting to the Amazon review as well.
