I bought the cable to transfer data between a satellite receiver and PC exchange. The cable that I had misused to date, had finally returned. I put the new cable to the receiver and immediately starts a transfer. Here then immediately came the disillusionment. The transfer rate was abysmal (approximately 3.6 MB / s). The transfer I immediately stopped and put in between my old cable. Otherwise I have not changed anything. Lo and behold, the transfer rate rose immediately to the usual 18-20MB / s. Conclusion: The cable is not recommended if you have a "USB 2.0" expects cable. Return is not worth, but I would advise against any of the purchase.
