Two usb serial output from one board (uno, mega or due)

Hi to all,
I need to split rc received strings to 2 usb, so I ask if there is a way to do that with a single board.

I tried with arduino due (native and programming ports) and I found that it's possible but when I read from one port, it automatically close the other.

I would try with an extra usb port on arduino uno as this:

but I don't understand if it's possible.

I only need to have two usb serial output.
tank you for any suggestion.

You could try something like this from Ebay.

Can I do a dual usb communication with such a converter?

With an UNO, you can use the hardware serial port for 1 USB and a software serial port with the adapter for the other.
