This usb-skeleton driver does not have any examples of interrupt or
isochronous data being sent to or from the device. Interrupt data is sent
almost exactly as bulk data is, with a few minor exceptions. Isochronous
data works differently with continuous streams of data being sent to or
from the device. The audio and video camera drivers are very good examples
of drivers that handle isochronous data and will be useful if you also
need to do this.
