Interesting, I almost bought that device until I found less expensive options. I was just looking at the Razer Support page for the Tartarus and they have this entry:

My Razer peripheral will not work properly when used with a KVM switch.
We recommend plugging your Razer product directly into your PC. KVM switches are known to cause interruptions in communications between devices and PCs. If your Razer product works when plugged directly into the computer, then it is working correctly, and the issue is most likely due to the KVM switch.

That is curious as further down in the FAQ they specifically address whether or not you have to use drivers. It suggests the thing should work like a regular keyboard without drivers.
