Thank you for your kind and quick reply. I'll indeed be using ```alsa-rs``` in the foreseeable future. I'll keep ```midir``` for development targets as timing or being hot pluggable are...

Hhhmm, I think Cpal kinda forces the programmer to sync to the audio streams. Which is kinda ok.. for me. Some jitter is to be expected. A non-realtime OS is...

Same here, and Linux support is even worse. I appreciate the work on the API to get the interface to be fool proof: the application programmer cannot just poke around,...

This is what you need to do.. It effectively means that device selection in Cpal/OSX is broken. You can only use the default system configured device. ![Screen Shot 2021-11-26 at...

@6by9 so should I post this on the raspberry/linux repo instead? To me it seems like the VL805 is cycling its VBUS, although I have not used an oscilloscope to...

The answer is no: the ```urb status -32``` flood doesn't destabilize the system, but of course it fills up the system logs.

@pelwell That's pragmatic, but otoh.. The VL805 itself is already a hub. And the Pi3B's hub doesn't suffer from this problem.

Indeed, this backpowering behavior is against USB specifications. It's best to not let this issue go philosophical. I'll accept that some device manufacturers need to do their homework, but also...
