* 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* - The USB_Device_IsUSBSuspended() macro has been removed, as it is obsolete.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_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().
