It is difficult to see that these internal cables and connectors on MBs adhere to the USB standard. By all accounts, these should be avoided for audio use.
As I have pointed out, the transformation from the A to B connector makes quite a lot of demands on how cables are laid out internally and how these are soldered to the plugs.
A new secure and impedance matched 'standard' for audio is called for.
Note: On my more expensive usb cable (Gemini) and iFi Power combination, the connections are so loose that I have had to crimp the plugs for a more secure mechanical connection. This does not guarantee that internal 'hard' contacts have been made.
