Thanks Chris. The PL2303 driver source run perfect in Linux desktop, and in Ubuntu Arm too. In Android system, after many fails and tries, I've manage to make the driver shows a ttyUSB0 in /dev, and are going to test the functionality.
Regarding piracy and pirated software you mentioned, I'm not sure they will provide kernel sources or not, it's a shame if it will be a real pirated software. The service people from the MID manufacture is included in this email.
