USB DAC doesn't work with powered USB hub?

    I just got a Patriot USB 3.0 Powered USB Hub. The thing works great for my other devices. It detects and charges my phone and transfer files. It won't detect my iBasso D2+ Boa USB DAC. The DAC works in any other USB port.

    Has anyone else encountered this issue and found a fix? The ground loop noise is irritating af. I need to get this to work.

    Interesting, it might not be able to detect the device drivers or something like that. Try plugging just the dac in by itself and see if it does anything. Does the device show up in devices or sound settings at all?

    This happens with my Anker powered USB 3.0 hub. It doesn't play nice with a my Fulla or Monoprice Desktop DAC. Others work fine. I have heard sometimes 3.0 to 2.0 is an issue with hubs and DACs, I have no idea why that is.
    castleofargh and astro like this.

    Yep, it works fine directly plugged into a USB port on the computer. It's just not working with the hub.
    I've tried the hub on a second computer and I get the same issue.

    Hmmm so I should give a USB2.0 hub a shot eh? Just ordered one from ebay. Hopefully this will do the trick!

    Possibly, can't guarantee that's the problem but it would be my first thought.

    Let try Elfidelity USB Booster III + iPower 5V/2A.

    The powered USB 2.0 hub works, but it doesn't get rid of ground loop noise. I'm not spending $70 to get rid of USB noise. I would rather sell my USB DAC and just get one that takes an external power source.

    Hmmm, the USB2.0 hub plugged into the USB3.0 hub allows for the USB DAC to be detected. The USB 3.0 hub is much better at clearing the ground loop noise. But I get crackling and popping issues during music playback.
