Cleaner solution to the PrinterHost data send routine problem of embedded NULLs - use a special structure to hold the data string plus the length in bytes of the data.

Fix unfinished printer host demo - some printer languages use embedded NULLs and so strlen() won't work in all cases. Ensure NULL terminator for the test page is not transmitted to the device.

Don't send terminal RESET codes via serial - just set the foreground colour and assume the user has the background set to something sane, so that the demos don't wipe out custom user terminal settings.

Use sane ANSI terminal escape codes for the Host mode demos, so that they do not cause eye-searing, unreadable text on terminals which parse the escape codes properly.

Change over Printer_GetDeviceID() to require a pointer to the destination buffer plus the buffer size, rather than using a pointer to a special structure.

Make new Printer_SendData() function to hide the implementation of sending data to an attached printer, cleaning up the main demo source file body.

Fix PrinterHost demo so that it will only enumerate printers with Bidirectional protocol encapsulation. Change enumeration code to automatically select the correct alternate setting for the printer interface to select the bidirectional protocol.

Fixed incorrect PIPE_EPNUM_MASK mask causing pipe failures on devices with endpoint addresses of 8 and above (thanks to John Andrews).

Magstripe Project: Ensure that empty tracks still print out a newline seperator so that the host always knows what track data is being sent.

Updates to PrinterHost demo to include some PCL test data plus fixes to the GetDeviceID routine.

Added new HOST_STATE_WaitForDeviceRemoval host state machine state for non-blocking disabling of device communications until the device has been removed (for use when an error occurs or communications with the device have completed). Changed over all host mode demos to use the new state.

Added verbose documentation for each of the USB Host state machine states.

Fixed Host mode to Device mode UID change not causing a USB Disconnect event when a device was connected.

Seperated out Lib components of the incomplete BluetoothHost demo application out into a seperate Lib subfolder.

Changed F_CLOCK entries in project makefiles to alias to F_CPU by default, as this is the most common case.

Pipe_ConfigurePipe() now automatically defaults IN pipes to accepting infinite IN requests, this can still be changed by calling the existing \ref Pipe_SetFiniteINRequests() function.

Fix makefiles -- the auto-addition of -D switches to each LUFA compile time option was faulty, due to GNUMake becomming confused by the spaces in the USE_STATIC_OPTIONS lines. Make user add in the switches explicitly instead.

Extend USB_GetDeviceConfigDescriptor() routine to require the configuration number within the device to fetch, to add support for multi-configuration devices.

Added new USB_Host_ClearPipeStall() convenience function to clear a stall condition on an attached device's endpoint.

Added new USB_Host_GetDeviceDescriptor() convenience function to retrieve the attached device's Device descriptor.

Make Pipe_ConfigurePipe() mask the given endpoint number against PIPE_EPNUM_MASK to ensure the endpoint IN direction bit is cleared to prevent endpoint type corruption.

Fix documentation mentioning Pipe_GetCurrentToken() function when real name is Pipe_GetPipeToken().

Changed per-device controller preprocessor checks over to per-device series for better device control.

Fixed error in Endpoint.c using HSOFI rather than SOFI for counting elapsed milliseconds.

Fixes to the MIDI device demos (ClassDriver, LowLevel); discard unused read-in events from the host, use standard MIDI event structure in low level demo rather than sending individual bytes.

Converted Host mode demos to schedulerless. Fixed host mode broken due to earlier Start-of-frame event experiments.

Copy and convert incomplete Bluetooth Host demo to the library.
