Did you try eliminating the power supply completely? Since Devialet does not need/use 5v of the USB, and if the device is using the power supply just for this, maybe it works without it? Can you check?
Thanks
Never mind...
I just RTFM'd the FAQ and found this
Once you are certain that no 5VBUS is needed, then yes, you can run the REGEN from a 5V or a 12V supply. The main function, USB hub chip signal regeneration and impedance match runs off of 3.3V from a separate ultra-low-noise regulator, thus 5V input allows for plenty of drop required for that regulator to do its thing.
Apparently you still need the power... but a crazy thought would be to use a simple clean 5v battery supply just for the signal regeneration and impedance match...
cheers.
I agree Kunter. I've read the same about the 5 and 3.3V. Regen does respond to better power so a battery may be the right thing. We'll see what turns up.
