This sounds great :-)

I see that in the patch usb2 is not enabled in the kernel by default.  Is 
there a timeline for it to be enabled and/or could you provide an alternate 
kernel config with usb2 enabled (temporarily)?

Lastly, is there a web-page where one can check up on the progress of the 
integration of the new code (and the removal of the old code) [preferably an 
up-to-date web-page]. 

Thanks for the great work
