Kobo and Windows 10 Aniversery update

I cannot use Calibre with my Kobo H2O since upgrading to the newest Windows 10 upgrade from august 2016. On my computer i can see the Kobo as a usb drive but i cannot read books or put new books on it.
I tried it on several computers with the newest upgrade and with 3 different kobo readers. They all have the sane problem. I assume there is something very wrong with kobo and the last windows upgrade.

Anyone knews a solution??

Thanks in advance.
