Question: How do I have control of two PS2 mouse independently from the output of KVM extender. My problem is only one PS2 mouse is working. I cannot get the other PS2 mouse to work independenlty. Is there any product available such as "A and B switch to make it works?
Answer: Thank you for your inquiry,

With PS/2, mouse and keyboard ports are different (on your PC and on the extender). We also actually tested this implementation by gerry-rigging two PS/2 mice into correct ports on a PC, and neither mouse worked - It seems like the PS/2 specification does not support two simultaneous mice.

To accomplish this, you should be able use a Reverse PS/2 KVM Switch (KVM Splitter), such as the NTI VOPEX-4KVIM-A for switching the PS/2 source - Video connections shouldn't be required.
