I know this thread is rather old now and you might have either solved or given up on the problem, but I’ve just bought the Huntsman v2 Analog, and after installing it, the World Map on MSFS would simply not stop moving.  Like for you, it looked like the virtual xbox controller had been activated, even though I had typing mode activated in Synapse and hadn’t touched the virtual xbox controller settings.

Having tried quite a few things, without success, I tried binding keys to the virtual xbox controller’s stick and bumpers.  Having done this, I was thankfully able to stop the World moving and the issue still didn’t recur when I reversed out those bindings.

Time will tell, but this makes it look like Synapse might not have been initialised correctly, when it was first installed on my PC and looked to be leaving the virtual controller partially activated and in a rather weird state.

If you’re still having the problem, maybe just try binding and then unbinding the keys to the virtual xbox controller.

By the way, I’m guessing that the two keyboards use the same software, within Synapse.
