That's great, which project is doing this?  What type of USB driver are
you needing to create?  A "gadget" or a "normal" driver?  What hardware
is this for?

What's wrong with the ones we already have that do this?

Not much has changed in the USB core to need to update those, what have
you found that is lacking?

Any reason why usb-skeleton.c isn't a good example?  I like it :)

Also, USB specific Linux questions should be asked on the
linux-usb at vger.kernel.org mailing list, as that is where all of the
Linux USB developers are at.
