The micro is good, but the cable was saved. The repeatedly occurring in this device reports errors in the USB detection may have a loose connection in the cable connector as a background. I had the problem also, oddly enough, only after some time. At first everything went well, Windows refused increasingly recognizing the USB device. For a while, helped re-plugging the small Steckerchens on vocals, but when I re pocketed the big cable connector on the PC, it was not successful. Even the "smelled of hardware", as the saying goes. Finally, nothing went - the light at the micro remained constant in yellow: "USB device not recognized". But I noticed that when inserting the small plug on the micro LED momentarily shone blue and with little movement of the plug again went to yellow. Everything interpret but very on a loose connection. So I joined the micro trial basis with the USB cable of my digital camera (fortunately has a standard micro connector). And behold: it was, and it still goes. So: When buying a few euros for a better cable schedule, then it probably works too! May the producers read this review.
