* - Internal USB driver source files renamed and moved to ease future possible architecture ports
* - All internal pseudo-function macros have been converted to true inline functions for type-safety and readability
* - Changed LED indicator masks for the AVRISP-MKII project, so that there are defined roles for each LED
* - Altered the CDC Deivice and Host Class drivers' receive byte routines, so that no data is indicated by a negative return value
* - Added auto flushing of OUT data to the CDC Host Class driver's USBTask function to automatically flush the send pipe buffer

* enhanced \ref USB_Device_SendRemoteWakeup() function. Existing code may now discard any checks to USB_Device_IsRemoteWakeupSent().
* - The USB_Device_IsUSBSuspended() macro has been removed, as it is obsolete. Existing code should compare \ref USB_DeviceState
* to see if it the device is in the \ref DEVICE_STATE_Suspended state instead.
* - The \ref CDC_Device_ReceiveByte() function has changed, and now returns a signed 16-bit integer, with -1 indicating no data was
* received. This allows for more efficient coding, as a call to \ref CDC_Device_BytesReceived() is no longer needed if the exact
* number of queued bytes received is not needed.

* - The \ref CDC_Host_ReceiveByte() function has changed, and now returns a signed 16-bit integer, with -1 indicating no data was
* received. This allows for more efficient coding, as a call to \ref CDC_Device_BytesReceived() is no longer needed if the exact
* number of queued bytes received is not needed.
* - The \ref CDC_Host_USBTask() now calls \ref CDC_Host_Flush() automatically, flushing any queued data to the attached device. Manual
* flushing of the interface is no longer needed if the flushes should be in sync with calls to \ref CDC_Host_USBTask().
