First, super, then scrap

First, the adapter worked very well. The known problem cases at low cost adapters (ie) was mastered without any problems, as the 19 extra keys on my keyboard (layout to a Microsoft Natural Keyboard Pro). In the BIOS there were no problems.

After approximately 4 weeks, so after the expiry of the return period, then suddenly began to control LED of the Num Lock key to going out sporadically, although NUM-Lock has been active as before. The next day also began the mouse, at ever shorter intervals, unmotivated to jump around the screen, the text has been selected, clicking buttons, pop-up menus appear. That was the time for me to disconnect the part again. I am a software developer, the risk that a crazy mouse me accidentally delete or change source code, I was far too large.
