Did the end of September 4 of this USB extensions bought, as these short extensions on the one hand are often very practical, on the other hand also prevent damage to a stick or the respective boards in the computer. Here is today on Amazon the only one I've found. At the first connection, I realized that a flash drive was not working, I think the cable connector does not go far enough into the socket on the PC or a hub into it, at the end of the road there is no "click", but you get the impression to land on rubber. I then 2 of 4 pieces returned, because I found the other two would function adequately. A few days ago I wanted to drive a stick into the laptop, but the operating system meant that I had to stick format first - which of course was not true, because without cable it worked, but only after rebooting, because the stick was completely wrong tight reports and an ex - and then reconnect then nothing helps. Have now called Amazon because the normal return period is indeed expired and get the documents to return - everything ok. So also with me contact problems, the ratings had not previously read and see only now that they occur in others. It is not in my opinion (at least in my sticks) on the clutch side, but on the connector side as described. Conclusion Therefore, unfortunately: Only very limited useful when the socket fits in the PC (to a hub with me It's not at all) and the stick can be friends with it. In Delock you should know, my impression is, it is up to the cable connection in the plug itself, which at the thicker USB 3.0 cable probably need more space than that of USB 2.0 actually.
