For some odd reason, my Roccat Kone XTD gaming mouse likes to disconnect by itself when I plug in, disconnect, or otherwise manipulate other devices that are attached to my computer. That includes such mundane things as touching a cable to a USB port (without even plugging it in) or probing a USB battery charger connected to the computer with a multimeter. It isn't happening that often, but it's annoying me enough to ask this question (and Google hasn't been very useful here).
When this happens, the mouse seemingly turns itself off and Windows gives me a "USB Device Not Recognized" error. Clicking the mouse restores the connection. On rare occasions, my Roccat Isku keyboard will reset itself as well. No other USB device I use exhibits this behavior.
The nature of this behavior makes me think the problem lies in the mouse not tolerating noise from the electrical ground of the computer. Aside from replacing the mouse, is there something I can do to address this problem? What might be the cause?
If this helps, the computer is a Sager NP8255-S (Clevo P157SM) running Windows 8.1 Pro. Updating the mouse's firmware did not help, and all drivers are up to date. Roccat Talk is installed and up to date as well. Event Viewer doesn't show any relevant events.
Initial question: Have you installed the latest Kone driver? You might also need the ROCCAT TALK driver.

Note: I had today a strange case when connecting one USB disk suddenly disconnected another one. Re-plugging the second disk fixed the problem. This now looks to me like only partially relating to Roccat hardware, more like a problem with Windows that is triggered by something to do with USB. Try to change the USB ports, or between front and back ports of the computer (if you have them), to get more information about the required conditions for it to happen. – harrymc – 2014-12-19T20:45:23.873
