Works OK with one PC but with KVM Switch may be a problem
on 1 December 2013
This does what it says on the tin and will work when it is used with one PC however if you are hoping to use it with a hot key to change PCs via a KVM Switch you may have problems.
I have a 4-port PS/2 KVM (of the Chinese Purple-cased variety) that switches PCs with a keyboard hot key sequence. This is Scroll-Lock twice for a beep and then Cursor-Up or Down to change PCs. Strange thing is it does work sometimes but more often not. I'll be on one PC and then change over to another and it will change then change again then freeze for no apparent reason and on a PC upon which it worked before. This means I have to scrabble around under my desk to use the manual button on the KVM. I tried using an (optional) power supply with the KVM but it made no difference.
I can't say if it will work or not with your own KVM however and to be fair, it does work well with one PC which is why I gave it a 3-star "OK". From reviews I read I had higher hopes fr this adapter though.
I have replaced one of my 4 PCs recently with a new build and there is no PS/2 on the motherboard, just USB. Next I'll try a PCI card that provides two PS/2 ports for mouse and keyboard; I have a spare PCI slot doing nothing right now. I'll write a review on that and let folks know if it works or not. It's sold on Amazon and you can find it by searching for "PS2 and PCI". I've never been that keen on USB connections for mouse and keyboard. I'm in IT and have always found PS/2 to be rock solid whilst I've had many problems with USB mice and keyboards, especially with OS installations on new systems - W7 hasn't given me problems yet but XP and Vista can be finicky.
[UPDATE: The PCI card works a treat it's just like having native PS/2 on the motherboard. Old-style KVM users out there may want to go down that route to avoid compatibility problems]
