* After the inclusion of the master USB driver header, one or more of the following tokens may be defined, to

|
* allow the user code to conditionally enable or disable code based on the USB controller family and allowable
|
|
* USB modes. These tokens may be tested against to eliminate code relating to a USB mode which is not enabled for
|
|
* the given compilation.
