Summary: This thing drove me crazy until I figured out it wasn't my platforms it was this switch! Went back to a 10 year old StarTech 4 port switch for my older platforms and went with an IOGear 4 port switch for my newer platforms. TK-407K HW: v1.3R purchased June 2014.
Cons: * Doesn't properly manage USB states to the devices or to the computers. * No Linux Support * Num Lock (not just Scroll Lock) causes session switch. Imagine how fun that is if you are a heavy numeric keypad user! * Randomly crashes all my platforms (Windows and Linux)
The TRENDnet KVM switch is a great addition for my setup

Summary: The Item was as described. It contained all of the necessary cables and works well. I use it to connect to my old P4 BioStar VIA computer (Home Built) Win 7 32 Bit and my much newer HP Compact 8200 Elite SFF with Intel I-5 2400 CPU Win 7 64 Bit. I am using an old Acer AL722 17 inch Monitor.
Summary: I love the price but I have had a few hiccups with it over the past few months. I fix computers for a living and half the time while I have 4 machines plugged in, the keyboard and/or mouse will randomly stop and start working.
Summary: There are some issues when firing up one PC and then later firing up the other. Sometimes it "forgets" how to switch from one to the other, but resetting the switch by pulling the main plug and plugging it back in, usually works.
Summary: I am using this for three laptops: a Dell, an HP, and a Lenovo Helix. I have a VGA adapter for the Helix. It switches between the three smoothly. I haven't had a problem with any not being recognized when I press the button to switch.
