I fail to understand how you can measure keystroke latency coming from a KVM. Everything behind the KVM is invisible to you, assuming that it is spoofing a legitimate logitech dongle and emulating a legitimate screen edid.
The KVM uses buffering and queues the keystrokes. So the net time between them is the same as if I would type them locally.
What you could measure is the fingerprint of USB initialization and enumeration of keyboard, mouse etc when connecting and starting up.
