Communication lost with a radio connected to an Android tablet

Hello world,

It is my first post here. I’m requesting help to resolve the following issue.
On Acer Android 7.0 tablet, I launch qgc. qgc says “Waiting For Vehicule Connection”.
I plug in a radio telemetry in mini usb port.
I get this message:
Error on link /dev/bus/001/002. Error connecting: Could not create port. Cannot send after transport endpoint shutdown

Best Regards.
