Move out private/internal host class driver constants to the common class driver headers, so that they can be used in the Low Level host mode demos.
Ensure all demos, projects and bootloaders use the class driver constants where possible to minimise code repetition.
Small documentation improvements to explicitly reference tokens in Doxygen, to ensure that they are converted to cross-reference links in the output files.
Update the pipe configuration routines in the host mode class drivers so that they use the same new code to enumerate compatible devices to increase reliability. Add support to the host mode class drivers for non-sequential (but non-overlapping with other interface) pipe numbers.
Add new module source variables to the library core makefile, so that module sources can be added to a project's makefile on a per-module rather than per-file basis.
Renamed internal Host mode Class driver descriptor comparator callback routines so that they all start with a uniform DCOMP_{Class Abbreviation}_ prefix.
Add the beginnings of a SDP implentation to the incomplete BluetoothHost demo.
Add const attribute to the Mass Storage Host driver functions where it was applicable, but missing.
Added brace guards to macros with parameters to prevent unintended changed evaluation of the macro expression.
Minor code cleanups (remove redundant comments, fix spacing, etc.).
The USB target family and allowable USB mode tokens are now public and documented (USB_CAN_BE_*, USB_SERIES_*_AVR).
The SCSI_Request_Sense_Response_t and SCSI_Inquiry_Response_t type defines are now part of the Mass Storage Class driver common defines, rather than being defined in the Host mode Class driver section only.
The USB_MODE_HOST token is now defined even when host mode is not available.
Added missing CDC_Host_CreateBlockingStream() function code to the CDC Host Class driver.
Descriptor processing routines now pass around void pointers rather than uint8_t pointers, as their destination datatype is know well known -- they are just streams of bytes until they are cast to the correct destination type by DESCRIPTOR_CAST.
Add new manual pages detailing the advantages of LUFA over the official Atmel USB AVR stack, and reasons why LUFA should be used over a built-from-scratch USB stack.
Fix KeyboardHost ClassDriver demo; boot protocol keyboard report structure in the Host Mode HID Class driver uses the full keycode array from the attached device.
Add more skeleton functions and definitions to the Mass Storage Host mode Class driver.
Made Endpoint_Write_DWord_* functions echo the structure of the matching Endpoint routines for clarity.
Added ATTR_NON_NULL_PTR_ARG() attributes to the class drivers to improve user code reliability by disallowing explicit NULL pointers as pointer parameters in function calls where the parameter must not be NULL.
Disabled building of the Demos/Host/ClassDriver directory until Host Mode Class drivers are complete to prevent build errors in the meantime.
