When I use the function 'serialportlist' to identify the serial ports on my laptop i get a 1x0 empty string array.
ports=serialportlist
ports =
1×0 empty string array
I think, I should get at least 2 ports, because I have 2 USB ports on my laptop.
Im using matlab 2019b.
Do i need to instal some packages for using serialportlist?

USB by itself is not enough: you would need to have a connected device that is responding as offering a virtual com port.

USB speakers would not advertise themselves as offering virtual com port services so using serialport() would not be appropriate.
