They actually sell this?

Anonymous, Newegg
21 May 2014
  • Summary: You'd think they would apply some QA before selling such items. It will be my last Linkskey, that's for sure.
  • Pros: Video switching works.
  • Cons: The USB ports only work intermittently, and never during POST of the host PC, so I need a USB port for KVM power, but still a USB switch to actually use USB. If running Linux, the USB port being dodgy can be seen through dmesg.

Works OK except for hot keys

Gregory W., Newegg
13 November 2013
  • Summary: First time I've ever seen a switch that requires an OS to be running for the hot keys to work. That is extremely annoying. But it was easy to set up and it works well.
  • Pros: Does it's job, does not require a power cord. Comes with all necessary cables.
  • Cons: Hot keys only work in Windows (not in Linux or while in the BIOS). Feels a bit flimsy, I hope it's more durable than it looks.

A trick to reset LKU-S04ASK

Hiroshi N., Newegg
4 July 2013
  • Pros: Just works fine. As I know the trick described below, I am completely happy with it. Actually, I bought two more for the use at different places. They are al working fine.
  • Cons: For over 3 years of use, it stopped working once. After some struggle, I found a trick which is nothing but power recycling (like any other USB device). As its power is fed by the USB cables, tuning off PCs on their front panel is not enough as USB output may stay. I did it by switching off the master outlets surge suppressor to turn off all the PCs connected to it. So, what’s the cons? This trick was not explicitly written on the manual (probably it is so obvious).

Works for me

rar113, TigerDirect.com
26 February 2013
  • Summary: My old PS2 KVM switch didn't have a button-press method to switch computers. You had to press scroll-lock twice and then 1-4. I prefer buttons. This has scroll-lock too, but it just cycles, 1 then 2 then 3 then 4, so I don't use it. Haven't even installed the software so can't evaluate it.

Bad desing of the switch

PHILJANS, TigerDirect.com
21 February 2013
  • Summary: I just spoke with their tech support and they confirmed it: The switch is design so that every single time you switch from one computer to the other, the computer you leave detects the keyboard and mouse as unplugging and the computer you go to detects it as NEW DEVICE! So every time you switch all computers beeps for nothing and you have to wait for the autodetec to install the mouse and keyboard and sometime you get stuck without the mouse or without the keyboard or...

Taking a lot back from my last review

RG G., Newegg
2 December 2012
  • Summary: Gonna have to get another one, the numlock idiocy is annoying, but having to manually power down is for the birds.
  • Pros: See previous review by me
  • Cons: I thought I had a screen blanking problem on my HP computer. Turns out, this device just really screws up like 60% of the time. I have to unplug EVERY USB to EVERY computer so it powers down, then plug them all back in again and then it recognizes everything. Until I turn off the computer. Next time I turn it on, unplug ALL the USBs.

Weird VMWare behaviour

Troy, TigerDirect.com
30 November 2012
  • Summary: I tried to replace several older PS2 KVMs with these USB models. I ran into an unexpected behaviour when using them with vSphere Client 4.1. When ever the keyboard-mouse control is passed to a VM from the desktop, the KVM detects the keyboard-PC as not there anymore, and immediately switched to the next PC on the KVM. I found no solution other then to go back to the original KVMs. I was happy with their cost-feature set, cheaper then old PS2 models with cables!

Almost great, but numlock poor choice

RG G., Newegg
24 November 2012
  • Summary: If you don't do a lot of numlock on then off, then this product is perfectly designed and works perfectly. When only one computer is on, the numlock thing blissfully doesn't work.
  • Pros: Love the USB withing the VGA cable (a lot less to plug in). It's VGA at the box end and VGA + USB at the computer end. Connection cables are seperate, so you only use what you need. And everything works just great - picture quality same as without KVM.
  • Cons: It has buttons on the box for which computer, but it also lets you switch between active computers by SLOWLY double tapping numlock. Unfortunately, I'm writing, I hit numlock to enter numbers, then hit numlock again and I'm looking at the wrong computer. Here's the horrible part - I switch back and it takes a full ten seconds before Keyboard & mouse come back. Very frustrating. Should use scroll lock and let MAC users hang.

Image both clear AND blurry

William P., Newegg
22 August 2012
  • Pros: Inexpensive; buttons make it easy to switch between systems; cables are included
  • Cons: The video clarity is fine with some systems, but it adds mild blurriness with others. The systems with blurriness are NOT blurry when the monitor is plugged directly into them. It's not a showstopper; I'm typing this on one of the blurry systems now. But it's annoying. I've tried other monitors with this KVM, but they didn't make a difference. They were clear with some systems but blurry with others. It's not particular KVM ports that are blurry either; I can put a cl...
