Isochronous USB transfers on RPI?

[Jakob Alvermark]

Hi,

Maybe this should go to the usb list, but it is probably relevant here as well.
I have been playing with the Pi for a while now and having great fun with FreeBSD.
Great work gonzo and others!
However, I'd like to use a webcam with it. I learned that USB webcams use isochronous transfers and the DWC OTG driver doesn't fully implement it.
(If I read the commit logs correctly)
What is missing and how can I help?

Best regards,
Jakob
