Η απάντηση της m2tech για τον driver της, στο mail που έστειλα:
"Dear Customer,
as you know, there are problems with OSX 10.9 (Mavericks) and some M2tech products. We still don't know the causes, but we're actively investigating to dicover and eliminate them. In fact, 10.9 is supposed to act same way as 10.6/7/8 with USB, but it doesn't. we're trying to find out whether this is desired or it's just a bug in the beta version of Mavericks everybody is using today. As soon as we'll find it out, we'll advice. Of course, if this feature is desired by Apple programmers we'll update our driver according to it.
Many thanks for being patient!
Best regards"
