OK, thanks for the tip... How do I do that now?

After having bought my new (proud, proud!) Win 10 computer, I had to buy a new Midi interface because the old one was not working anymore... So this midi interface is relatively new (I bought it in Sep 2019)and it has (as far as I know) no driver in the packing. It is a "plug and play" interface.
So I tried to plug it out and in again, but it seems that BiaB "doesnt care". No effect.
How can I revive it?
