Launchpad S loses midi connection after a while

On windows 10 here, it seems like the launchpad S loses its midi connection with Renoise after some time of non usage, while my alesis v49 keyboard always keeps sending out midi.

Is this a known, common problem with the launchpad S? Anyone with similar experiences?

For now, hotplugging / rescanning seems to get the job done, but I rather like not to all the time.
