Hey,

I saw your the thread about comport error with Win10 on the archive of the
forum, and I don't know how to answer it.

I had the same problem and I just installed the last update of Win10
(https://www.microsoft.com/fr-fr/software-download/windows10) and it
solved my problem.

Hope you'll be able to forward the fix to the forum.

Cheers,

Maxime.
