Mouse and Keyboard hooked up with KVM switch does NOT work

November 25, 2013 at 05:19:06
Specs: Windows 64
Hi:
Two computers with XP were hooked up with KVM switch and you all know abot KVM switch, there is one monitor, one keyboard and one mouse to able to manuver two different computers.

The monitor works on both computers, however the mouse and keyboard does NOT work on one of computers/XP while the exact same mouse and keyboard working on the other computer/XP.

In my attempt, I used other, different type of KVM, but it still the same. both mouse and keyboard does NOT work on one of computers/XP, only Monitor to work on.

Just wonder why the exact same mouse and keyboard hooked up with KVM does not work on one of computers/XP while the other computer has no problem?

Thanks for your help in advance

As I read your brief "specs." info above you seem to running XP is 64bit mode?

What make and model of KVM are you using…?

Are the keyboard/mouse usb or ps2 connection?

Just to clarify: you're running one monitor and one keyboard and mouse for two XP computers - via a KVM switch?

Which means two monitor inputs (one from each PC), one monitor output - to the single monitor; two keyboard and mouse "output" connections (one each to each PC) and one keyboard/mouse "input" connection for the user… and which control whichever pc is selected?

If you connect each PC in turn to just one of the two sets of PC connections for mouse/keyboard (i.e. use the same, just one, of the PC mouse/keyboard outputs for each PC in turn…) what happens; and if you then repeat both PCs connected to the other/the second set of (output) connections (for mouse/keyboard) what happens?

Thanks for the response.
I need to clarify to the issue;
One PC is DELL which has no PS/2 slots on its back and I using PS/2 converter while the other PC, Acer has PS/2 slots on its back.

I suspect PS/2 converter on DELL has issue, not able to get mouse and keyboard work on.

My next question is; what sort of PS/2 converter do I need for DELL to get mouse and keyboard work properly?

"what sort of PS/2 converter do I need for DELL to get mouse and keyboard work properly"

It's most likely an issue with the converters or PS-2 mouse and keyboard and not the Dell machine. PS-2 devices need to be designed to use those converters and if they aren't, the converters won't work

I would get yourself a USB KVM switch, mouse, & keyboard and drop the PS-2 mouse and keyboard altogether.

mmm You have in effect confirmed what I was thinking… that there was a converter of some sort in the path for the problem computer…

Either you use ps-2 kit all the way (and in your case that obviously isn't viable) - or (as THX suggests..) you get a usb keyboard/mouse and and a KVM that also handles usb interfaces/connections. And ensure that "both PCs" can handle usb inputs for the keyboard/mouse…

I have found adapters for USB to ps-2 very much hit 'n miss too; some of them work and some of them don't… You "might" get lucky and find a pair that will work - but ???

Does the Dell work with a ps-2 adapter - not using the KVM?

What is the Dell keyboard/mouse input; and do the Acer and the Dell both have USB inputs.
