Galaxy a55 do not recognize USB mic

[Eduardo Lacusta]

My Galaxy A55 do not connect to a lavalier usb mic.
It seems de A55 do not power the lavalier receiver.
The A55 do not connect a ear phone using an adapter USB-C to P3/p2 as well.

Most of time it keeps mesaging "usb adapter connected" "usb adapter disconnected" continously while pluged.

Both the adapters and the phone connect normaly to the notebook and to the charger.

What should I do to solve this?
Many thanks

You may need a separate companion app to use the external USB mic.
