USB device not supported on S21+

[Heksmeester]

I've recently upgraded from an S9 to the S21 Plus. Since there is no longer any headphone jack, I bought an Aux to USB-C adapter in order to play music through my car audio system however I am getting the following error message when plugging in the adapter.


"The connected USB device is not supported."


This error pops up immediately after plugging it into the phone's USB-C port without being connected to the car yet. It does not appear when using the adapter with my S9.


Any ideas on what the problem could be?

I have exactly the same issue after also upgrading from the S9+ to S21+.

From what I understand the USB-C adapter must have its own DAC to work with the S21+.

I also read that you may have to turn on on the option "Disable USB audio routing" in Developer options for the adapter to work.

I currently have the adapter below on backorder from Geewiz which they say should work as it has a DAC:

Below is a link to an article that lists adapters that should also work:

I hope this helps
