Summary: Ok for all you people having problems, First problem is when you switch it takes forever. The reason you probably are having difficulty is that your power settings. If you are using the Basic power setting it has the usb selective suspending setting Enabled! Disable it and it should work properly.
Pros: This thing is great. Fast Switching if configured Properly!
Summary: I think I just got a bad unit by luck of the draw, it happens.
Pros: Nice looking unit with solid steel case
Cons: Unit was DOA. Hooked up to 2 PCs and 2 servers and 5v power supply -> port indicators lit up but no video, no switching. Verified video to end of new Startech cables and power supply had 5v with center positive.
Summary: Doesn't even come with the 5v DC adapter that is needed to power it. You would think an 80 dollar kvm switch would at least have EVERYTHING you need right out the box. Now I have to wait more days since I have to order that now. Disappointed.
Summary: I only unpacked it today, but it works great out of the box and has a sturdy construction. I was hesitant when picking a KVM but from everything I read about this one, it seemed like it would fit the bill. I have one Windows box, and 3 CentOS boxes all connected and can switch through them.
I highly recommend the SVUSBPOWER spare 4V DC power adapter from StarTech ...

Summary: I highly recommend the SVUSBPOWER spare 4V DC power adapter from StarTech for this. It doesn't make sense not to use it. Even though this product supports power through VGA or USB (can't remember which one), it did not work well for us and so I only gave this product 4 stars. Otherwise it's super!
Good equipment at a fair price. (4-port USB hub! YAY!)

Summary: This is a pretty good unit. I didn't know, however, that it required a special female to male VGA connection. Toher than that it works well. I does not come with nor require a power adapter (unless the computer your working with does not have USB.
Expensive once you add up the price of required "accessories"

Summary: Half a star off for cost. The problem is this requires cables to work, and maybe a power supply, plus ears if you want to mount it in a rack. The good of this is you can choose your cable length: 6 foot (p/n SVUSB2N1_6), 10-foot (p/n SVUSB2N1_10), or 15-foot (p/n SVUSB2N1_15).
Summary: I do not use the video portion of this switch as I have a need to see all PC monitors at all times so have 7 monitors on my desk. The use of the switch for mouse and keyboard were my chief reason for purchasing this switch.
