No. I am a bit confused indeed, according to dmesg uhub0 is usb3 and uhub1 is usb2, however if I attach the dongle to any of the four usb ports, I always see uaudio0 at uhub1 . In principle two ports should be usb3 (they are blu indeed) and the other two should be usb2. > Do you have a mean to plug the device on > uhub0 (the root hub)? none that I can think, I thought the usb3 was uhub0 > If so, could you try changing the block size by restarting sndiod with > the "-z <block_size>" option.

I need more time for this, I hope I can try today Thanks and best wishes Luca
