      As it reads in the description, mouse 1 is the input from driver, so for mouse 1 you have no special needs.
      For mouse 2, they dont talk about driver, they just analyze the input from another RS232 different from COM1, so COM2-x.
      With serial mouse, true RS232 works with voltages -12 +12, no TLL level. So if you connect a serial mouse to an serial 5V UART, the problem will come from the mouse. There are some boards that use MAX232, a chip that makes from 5V TLL 10V RS232.

        @dragu I'm not sure to understand all of that ... (on devrait peut être en discuter en Français sur IRC à l'occasion 😉 ).
        Perhaps there is confusion : Recalbox is installed on a Rasp Pi 3b, so the only ports I have, out of the box, are USBs.

          Le protocol de transmission entre une souris USB et une souris sérielle RS232 est différent, et donc déja là il se peut un problème. De toute façon, je doute que tu arrive avec une souris USB, aussi à cause du protocol. Les souris sérielles attendent un voltage différent de 5V. Alors il ya des Chips qui transforment +5V en - et + 10V. Comme le Max232. Si tu essai avec un câble USB - Sériel qui comporte ce chip, ça doit d'abord fonctionner sur une prise USB de ton PC. Après tu peut tester sur PI.
