If I go through a hub to force it to be USB 1.0, it works fine. Looking throught the ehci source seems to confirm that it just doesn't handles isochronous, and throws an error > > > Is there a new USB stack coming with high-speed iso?

I will take a look at uscanner, but if it uses ehci I will be in the same boat. > > > Is anyone working on a UVC driver?

Unfortunately, my cameras are not supported, and I'm looking to use UVC cameras, as I believe this will be the standard soon. Thanks Sam
