Are both devices generic that can be hooked up to any vehicle or are they specific to your model year vehicle? There's no common CAN messaging between the different OEMs. If they are generic and can be plugged into any vehicle and display data they are likely requesting OBD2 PIDs for their data, rather than just monitoring bus traffic. These OBD2 and responses from the vehicle will be on the same message ID and will probably confuse the two devices. Does the rest of the vehicle wig out when they're both plugged in? If the rest of the car is fine, I don't think there's a CAN wiring/termination issue, just a problem with the two extra devices.
