. . . there should be nothing to receive the 5V line at the other end.I've had two DACS (LKS and Musetec) that provided the 5V internally to their USB to I2S board. I tried blocking the 5V as per Abe, and it made no difference at all.
This sort of arrangement has two advantages. First the 5V provided to the incoming board can be as clean as the designer wishes and designs for. In the case of the Musetec it is provided by a bank of super capacitors.
Second, the data lines on the USB cable are thought by some to be compromised by the 5V running through the cable. Hence the various designs in some cables separating the 5V line from the rest.
