By the way:
I installed PEP1 and PEP3 on my business Notebook (Dell Win10 Latitude 7490) and connected the Pronto.
And it worked "out of the box". I didnt even had to deactivate HIDs. Strange thing.
So i could download the latest File to the Pronto but of course i want to establish the connection via my PC again. I will try it via the Docking Station and maybe reinstall the PEP-Software once again, if the Docking-Station isnt the solution.
=> The Problem has no high priority anymore, cause i have a workaround, but i still want to fix it.
