This error is expected. xhci(4) does not support isochronous transfers
yet which are required for 'real-time streaming' data like video/audio.
This is being worked on. I hope to get this working in the coming months.

Ok, is there any port which will just make a photo without this dumb "real-time streaming"?

[backrow]

It’s an issue with the hardware drivers, not the application itself. If this is the problem I’m thinking of, you can work around it by plugging the webcam into a USB 2 port.

[acampbell]

I get the same error when plugging in a webcam to usb-2.0.
