transfer switch problem

[nbucska]

two new 4 pos. "data transfer switch"-es,unknown and unmarked MFR,( contains 4 pos,multipole rotary switch only, used to switch monitor and keyBd to 3 PC-s, separate mouses) failed after few days:

Most of the times after switching PC, the mouse don't work on one computer until it is rebooted.

Is there any way --e.g. adding a pull-up -- to solve
the problem?

That, I think, is a problem with the OS.


I've tried swapping PS2 mouses and have always lost control of the pointer afterwards. USB mouse interface seems better behaved.

I agree with IRstuff, a manual switch will not work and I think there is more to it that just adding pull-up resistors.

Google for "KVM switches"

(Keyboard, Video, Mouse) - these have built-in electronics to fool the computers into believing they still have the 3 devices connected. I used one of these in a previous job and it worked ok. The biggest problem is remembering which computer you're shutting down!

They're not cheap, either...
