I just recieved a shipment of equipment orderd by my predicessor that includes brand new Dell Optiplex 990 computers, with standard mice and keyboards. Also included were Black Box ServSwitch Secure KVMs.

I've worked with KVMs before and hypothetically they should be the easiest thing in the world to deal with, plug it all together, push the button, go.

However, for the life of me I can't get the computers to recognize the mouse or keyboard when plugged into the KVM. We've seen this with multiple KVMs across the order.

Any one know what I'm missing?

Computers are all Dell 990 with Windows 7.

Are you using the right cables for the switch? I know that some of the Black Box switches require special cables. – Nils Magne Lunde May 22 '12 at 11:18
We are using Black Box brand cables, which are also brand new. – MrWizard54 May 22 '12 at 15:25

You must use wireless keyboard and mouse, such as Logitech wireless keyboard and mouse with Unified receiver ? or Microsoft remote desktop wireless keyboard and mouse sets?

Most of the KVM switch which based on USB keyboard and mouse emulation technology can not emulate the multi-function or special USB wireless communication.

The only solution for Logitech Unified receiver/ Setpoint/ Control Center now in the market is KVM switches with USB DDM (Dynamic Devices Mapping) technology or pure USB HUB-base USB port

updated on 12/18/2013. Confirmed that Black Box ServSwitch Secure KVM which is a hub-base class KVM switch having issues of unstable USB device sharing and created USB HPD errors.
