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.
Like @Digital_Dude says, conduct a test on the cable, resistance and continuity (some multimeters do both at the same time). Most curious though (no pun intended) is the USB that came with the Quest works with your Mac, it’d suggest not a cable fault. Sounds silly, did you fully insert both ends of the Curious cable? Did you try all RPi USB ports?
Also, not that it should affect it, what power block are you using with the RPi?
(Smoke me a kipper, I'll be back for breakfast!)
I owned a Qutest a few months back.
I had zero problems with any USB cable I tried connecting to a Sonore Ultrarendu.
This included el cheapo printer cable, Audioquest Carbon, Audioquest Diamond, Pangea, Straight Wire etc.
I’ve had a Qutest for a couple of years now and have had no issues with a couple of usb cables, a couple of laptops > Qutest, servers > Qutest and network transports > Qutest all over USB… As I understand it, the Qutest has quite the galvanic isolation and secret sauce to reduce noise ingress thanks to Rob Watts… I would look to the cable first then the RPi transport…
The cable works immediately when connected to my Mac Book Pro, yet definitely seems to not work when plugged into the pi. I’ve also tried to play through Spotify using RoPiee XL and with the Curious cable, no sound, but it recognizes the RoPiee (since Spotify Connect doesn’t need to see a DAC) if I change cables it works, most of the time.
While at first I was having intermittent issues with the stock cable as well, I re loaded RoPieee and it I consistently get a good connection with the stock cable. So, yeah, does seem like the cable doesn’t work with Rasberry Pi. I have an email out to Curious, but sounds like they’ll tell me the same thing as you @Anthony_B .
Hi Andy, just saw your post, no Volumio is my least favourite platform.
I predominately use only ropieee and occasionally for fun I will build an LMS server.
I have the curious cables were they need to be (Innuos MK3 mini server, Innuos PSU, into an OPPO HA-1, everything sounds very good so I have stopped tinkering.
