If you can get some logs, it might help. Also, you can try connecting with wire once and then using the dongle and see if that helps?

Yesterday I tried to connect after the cable but nothing worked. But today I connected to get the logs and everything worked fine right away. But in the beginning it always continues to write USB1 the device does not respond, I understand that at the moment of loading OTG will be transferred to the Dongle state but does not yet have a signature or ID. I couldn’t get the logs because the file contains a lot of information about the data transfer. You can add the nano test editor to the repository. I send log late with out connect phone I want to check the work as a whole now

With b58cc9d9bfc83215549438a7f0cec10b97bf920b, the verbosity of the logs should be reduced a lot.

@sacredneobi were you able to resolve the original issue? If not, you can try the latest version and share the logs if it still doesn't work?

I have the same issue that happens randomly. (Also Mazda 3) I'm using the latest version.

So on Mazdas, it connects automatically to the last connected device, in this case being the USB port.

What I suspect is happening that's it's trying to connect while the Pi is still being start up and initilaized and that throws "the USB device not responding" error.

I wonder if there's a way to add a delay to the USB port OTG capabilities, so that the Pi boots up with the car but the car won't recognise any USB device until the delay is over. (Maybe as a env variable so it's customisable, so those who don't need it can use the default value of 0.)

Looks like this might've been solved from the comments on the linked PR. Closing for now. Feel free to reopen as needed.
