Minor documentation fixes. Fix broken USB host mode due to the USB frame counter not being updated during the early enumeration steps, causing USB_Host_DelayMS() to spinloop forever.

* \section SSec_Description Project Description:
|
|
*
|
|
* Dual Communications Device Class demonstration application.
|
|
* This gives a simple reference application for implementing
|
|
* a composite device with dual CDC functions acting as a pair
|
|
* of virtual serial ports. This demo uses Interface Association
|
|
* Descriptors to link together the pair of related CDC
|
|
* descriptors for each virtual serial port, which may not be
|
|
* supported in all OSes - Windows Vista is supported, as is
|
|
* XP (although the latter may need a hotfix to function).
|
|
*
|
|
* Joystick actions are transmitted to the host as strings
|
|
* through the first serial port. The device does not respond to
|
|
* serial data sent from the host in the first serial port.
|
|
*
|
|
* The second serial port echoes back data sent from the host.
|
|
*
|
|
* After running this demo for the first time on a new computer,
|
|
* you will need to supply the .INF file located in this demo
|
|
* project's directory as the device's driver when running under
|
|
* Windows. This will enable Windows to use its inbuilt CDC drivers,
|
|
* negating the need for custom drivers for the device. Other
|
|
* Operating Systems should automatically use their own inbuilt
|
|
* CDC-ACM drivers.
