There's a potential source of difficulty right there. The Prolific chipset (pl = Prolific) has proven to be problematic on OSX systems; some of my experience is here. You may have better luck with a FTDI chipset or an adapter made by Keyspan.

But I have no experience with a touch screen, or the software they apparently require. Now that I think about it, even a Prolific adapter should appear normally in any lists of serial devices you might have - I'd expect it to look like it was going to work to the touch screen software, and then fail to send data reliably once it was connected, if you were going to experience the same problems I and others have had.

So, there - not much help, but at least you got a reply. :-)
