How did you try to use this?

        Is there a new USB stack coming with high-speed iso? Will it work with
ugen? If not ugen, how do I get at it?

My advice would be not to use libusb, just prepare your own kernel module. In most cases it is much simpler than ugen. Have a look at simple drivers like uscanner to see how to start with the USB kernel driver.

        Is anyone working on a UVC driver? I don't need all the features, just 
to
get at the stream data.
