If your requirement is a non-portable API that supports isoc on
Windows then libusb-1.0 currently does not work for you and your
choices are:

1. Help implement support for libusb0.sys in libusb-1.0 and thus
   close http://libusb.org/ticket/49

2. Use one of the Windows-specific APIs that Pete mentioned.

The former is obviously the only option that allows your application
code to stay portable. If this is not important for you then you
don't need to contribute to libusb-1.0 and can get what you want
using a non-portable API.

As Pete mentioned, USB2 vs. USB3 doesn't matter, but had you wanted
to use streams in USB3 bulk transfers you might have needed to work
with the API provider in order to create a suitable API for your
application, at least for libusb-1.0. This does not apply for
isochronous endpoints however.
