I liked what you said about a better driver from Prolific, so I downloaded and installed it.
But, when I attempted to updated my NCX to 302, at the end of the download, it gave me an "Update Error: The update is improperly signed.” . . . what do I have to sign?

In addition, on my eMate 300, I can’t change the serial speed above 9600 (I don’t have an Extras app either).

Any suggestions?
