Topic: Anyone got problems with USB galvanic isolator and ADI-2 dac fs (ESS)?
My ADI-2 and my USB isolator (BW Usb-to-fibre isolator, a Chinese boutique product) won't work together. The isolator does work as I confirmed using a few other dacs. There is ground loop in my system and I also want to lower power related noise for measurement purposes.
So I am wondering if anyone have experienced similar issues with their USB isolator, regardless of brand/make?
I am trying to see if the problem may be caused by a particular adi-2 firmware/driver version.
I have the ADI-2 dac fs ESS version, with firmware V5.1 harware rev 78 and the latest driver 0.9808. Also tried firmware v4.8 v4.9, and driver 0.9734 to no avail.

Details of my USB isolator:
The USB data isolation processor adopts optical fiber transmission isolation mode, where two separate units are connected by LC optical fiber cable. The data packets are transmitted in the optical fiber by the transceiver after serial parallel processing. It transmits usb data with reclocking.
This USB isolator is quite popular in Asia and there are reports that it works well with most dacs including the AKM4490 version of the ADI-2 dac fs.
Not sure if it goes against forum rules to post the link to store page so I won't.
