Thanks to @xiaoyaoyou for pointing this out here:
The ddHiFi cable is working just fine. I’m not sure if it’s a tiny jewel or will prove to be less than that in the long run. It appears to be silver colored wire in a transparent jacket with small USB ends showing the ddHiFi graphic. There are no indications of directionality, and it worked first time the two times I connected it. For $19, it is way more elegant than the AudioQuest DragonTail. If Sabaj packed these, it would take a lot longer to find out about the USB issue.
