Its definitely /dev/ ttyACM0 when plugged in. Not a USB something. I note from the web wiki you posted before (thanks) , two things, one being the mention of prolific, and most of their stuff is busted in odd ways, and it makes no mention of usb-2 compatibility, which is the case with these off- lease dell's I use for utility stuff or driving CNC machinery I've built, Their fastest usb is 2, No blue ports in a 4 pack of them.
