Ignitron Communication with USB cable

Strange communication issues with usb cables...cables to tablet I am trying to communicate with the ignitron ECU. You can see I have to add connections for some reason to connect on my tablet....any idea why less is not more....LOL ???

So apparently I can use any cable to communicate as long as I use an OTG cable at the tablet. Somehow that sets up the tablet as a host or sets direction transfer of data. Not sure if it is the tablet due to only having one USB port, or it is the version of windows. I never had an issue with the older laptop.
