|

* CDC Class Driver Description
|
||||
* ===================================================================
|
||||
* This driver manages the "Universal Serial Bus Class Definitions for Communications Devices
|
||||
* Revision 1.2 November 16, 2007" and the sub-protocol specification of "Universal Serial Bus
|
||||
* Communications Class Subclass Specification for PSTN Devices Revision 1.2 February 9, 2007"
|
||||
* This driver implements the following aspects of the specification:
|
||||
* - Device descriptor management
|
||||
* - Configuration descriptor management
|
||||
* - Enumeration as CDC device with 2 data endpoints (IN and OUT) and 1 command endpoint (IN)
|
||||
* - Requests management (as described in section 6.2 in specification)
|
||||
* - Abstract Control Model compliant
|
||||
* - Union Functional collection (using 1 IN endpoint for control)
|
||||
* - Data interface class
|
||||
*
|
||||
* These aspects may be enriched or modified for a specific user application.
|
||||
*
|
||||
* This driver doesn't implement the following aspects of the specification
|
||||
* (but it is possible to manage these features with some modifications on this driver):
|
||||
* - Any class-specific aspect relative to communication classes should be managed by user application.
|
||||
* - All communication classes other than PSTN are not managed
