Hi Paul, No it's not USB, I have added a card with two serial ports, so I have S0, the original port, then S1 and S2 which are the additional ports.
The reason was that on my control PC I am running owfs for 1-wire and also X10 to drive some outputs, so I needed two serial ports. In order to test out stuff I have added a similar card to my desktop and it is there that I am having these problems, the control PC almost never stops.
