Macros exist in each of the USBEndpoints_.h files for assigning default endpoints for bulk, interrupt and isochronous functions. These macros are used by the various device classes. The callback functions in the classes, however, are hard coded to specific endpoint numbers. I have added additional macros to alias the callback functions to ensure that they match the assigned endpoints for a given target.
All currently supported USBDevice targets have used the same endpoint assignments, so no problem has arisen. We are currently working on adding a new target in which the endpoint assignments will be different from the other targets and encountered this issue.
