We've had another user run into this. That user was getting 3mV artifacts when the participant simply moved their hand on the response pad.

The solution is to isolate the response pad's ground from the computer ground -- easier said that done. In the case of the other user, he supplied the response pad with battery power through the USB connector and collected the data on button presses via the Accessory Connector.
