The error does not seem to be a faulty mouse and I don't use a KVM switch anyway so it is not the source. Following on pervious reply, I tried on a new mouse. But was greeted with the same error:

Is there anyone here who uses a desktop setup with a mouse, not greeted with these pesky errors. Are experts on here sure this is not a bug, or lack of proper driver. More info on the latter, this test consisted of Logitech M90 and Dell MS111-P mouse.
