USB stick is not recognized because of wrong-worked connection

Something I have never experienced: After both the initial delivery and the problems provided by Amazon replacement product did not work 2.0 devices to the USB at my disposal, I suspected a non-standard implementation of USB 3.0 standards with the result the loss of backward compatibility. But no, the problem is that the recognition of the Transcend JetFlash 700 prevented, is clearly the physical: Apparently the stick is made with a high production tolerance that ensures that the USB port can be too deeply plugged into the socket. The result: The USB stick is not recognized. "Solving" this problem can be by again pulling the USB flash drive a short distance out of the socket. Can accept you as a manufacturer's sloppiness as a customer not.
