Can bus adapter not sending data

[Celestine]

After removing and restoring the ais connection the other week it is now the ais that sometimes don’t send data. Can bus is now ok but the ais (usb, nmea0183) needs one or more restarts is SK or like today, to remove and restore the SK connection.
Still no errors neither at system check, serial app or in SK.
It really seems like SK is screwing up the USB ports.
