@Daniel-RUIZ9 I may have found a solution to my problem, I have to test a few days to be sure. Hard my domoticz installation I have two raspberry one in server the second in client. The raspberry server is connected to the USB gateway and on the second I have configured the ethernet gateway. I keep you informed if I still have crashes.

I think you're right and it has a dialogue with a very specific protocol, but maybe my injector is too sophisticated, and a simple injector like the one in the photo does not support a dialog protocol.

Thank you for your help I passed the 2.2 satable version I am now launching on the ethernet gateway.
