My understanding is the Curious cable is not USB spec compliant, I think it was mentioned in this video: From about 5min in…USB Cables for Audio: Interview with Rob Woodland from Curious Cables - YouTube
Seems to be a mix of art and science… I.e. Designed by ear, trial and error.
I would try the cable on an alternate PC, if its not functioning, it could be a manufacturing issue. If you have a multimeter continuity test each pin.
I use an Oyaide Neo d+ Class A. Not the cheapest v’s generic, but its very well made and robust.
