Cross Posting this over here in the Qutest thread, since more qutest users may have some ideas and also may understand the use of a high end USB (or maybe not) but I already bought the cable and I wish to make it work!
I just received a Chord Qutest, and having read suggestions I picked up a Curious USB cable to go with it. I’m trying to use my Rasberry Pi as the streamer going into the Qutest via the Curious USB, however whenever I plug in the Curious USB it won’t show up as a device in Roon most of the time. Occasionally it shows up momentarily but then has difficulty connecting. However, when I use the USB that came with the Qutest it works fine. Additionally, if I plug the Curious into my MacBook pro and then to the Qutest, the Qutest shows up immediately, so it’s something to with the Rasberry Pi in the chain.
