USB Midi interface disconnected

[grego mondo]

Hello, have any one experimented midi interface (usb) disconected after a while ?
I'm trying to understand if it comes from a power problem or if it's due to inactivity in Usine.
I already experimented that it can happen with a powered usb hub or on the usb port of the computer.

Then I'm fighting with the "set up" to rescan and reset devices, untick and tick them again, unplug and replug the interface and it cames back but I can't find a routine that works quickly in case of disconnected interface.

Looks like the problem was Avast
