Hi, I tried to use the latest 0.17.0 with my raspberry pi zero 2w. Everything looks fine until it tried to connect as an accessory to the head unit (see logs attached). Or do I miss Interpret the error?

If this is not a problem with your USB cable or legacy_mode option, then can you please try if this is working fine in release 0.15.0?

Thanks for the quick respond. The cable shouldnt be a prbolem. I have tried 3 different cables in different lengths that all works as data cables with other devices at the desktop. Currently I am testing with a 20cm data cable.

Ich have tried with legacy mode disabled and the connection process seem to interrupt in an earlier stage (see log 0170 legacy disabled)

aa-proxy-rs_0170_legacy_disabled.log

I have tired the 0.15.0 release and have the same error.

aa-proxy-rs_0150_legacy_enabled.log

Also with legacy disabled:

aa-proxy-rs0150_legacy_disabled.log

Is there anything I can do to troubleshoot a bit more or provide more data?

Thank you already :)

Looking at your logs I think you just need the legacy enabled (this is the default).
In case of troubleshooting look here:
https://aa-proxy.github.io/docs/troubleshooting
And if you have linux/mac you can try Google's Desktop Head Unit (DHU), here's how:

Don't know what else I could recommend - for me it just seems like your HU is not starting transmission for some reason... I also know that VW units are sometimes problematic (even voltages on USB lines are sometimes out-of-specs)...
Sometimes the HU is cutting the power from device when it doesn't start AA transmission properly...
If you have more time to tinker - you can even try to start even older releases... maybe it would start?
