FPP - Renard output switching from USB1

[ebenne]

Hi Everyone,

I'm having an issue with FPP switching the output device for some Renard controllers from the USB01 (correct output) to AMA01 randomly throughout the night. Very frustrating and the first year I've encountered this. Has anyone else had an issue like this? How did you solve it?

Thanks,

yes. For me it was caused by cheap knockoff usb-to-serial adapters. They all have the same usb device id. every once and a while linux updates the usb bus bindings. When using the knockoff devices the os gets confused and reassigns the ports in unexpected ways. My solution was to use fixed bindings (defined hw path from adapter too os). In your case, I need to ask a question: Are you using an external USB hub? If yes is it powered?

Oh maybe that's it. I'm currently using this usb-to-serial adapter (and have been for 4 years): https://www.amazon.com/gp/product/B0...?ie=UTF8&psc=1

Weird that it's only recently become a problem for me. Which brands are the ones to look for? I'm unfamiliar with fixed bindings.. where could I learn more about that?

No, the usb-to-serial is plugged directly into the raspberry pi.

Thank you!

That is a fully featured adapter and would not have the problem I experienced. The next issue could be the adapter or USB connector has gone bad.
