title: Isochronous Read/Write with PyUSB
body: <p>PyUSB 1.0 claims to now support isochronous transfers if the underlying backend supports it.  I've figured out how to select the libusb1.0 backend which supports isochronous transfer, but I'm not sure how to actually implement reads and writes.  I've searched the Internets and cannot find an example using PyUSB.  Help?</p>
