Added new Endpoint_Null_Stream() and Pipe_Null_stream() functions.
Removed the NO_STREAM_CALLBACKS compile time option due to the new partial stream transfer feature replacing it.
Fixed errors in the incomplete Test and Measurement device demo preventing proper operation (thanks to Pavel Plotnikov).
Change over all low level host mode project's descriptor comparator routines to perform the descriptor casting in a temp variable to make the code clearer and easier to modify (despite being more verbose).
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.
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 CDC descriptor structs to the CDC class driver, so that the CDC demos can use human readable field names.
Rename prefix for Still Image Host class driver functions from "SImage_" to "SI_" to remain consistent with the rest of the driver.
Added new USB_Host_EnableSOFEvents(), USB_Host_DisableSOFEvents() and EVENT_USB_Host_StartOfFrame() for the user application handling of USB Start of Frame events while in USB Host mode.
Changed over all demos, drivers and internal functions to use the current frame number over the Start of Frame flag where possible to free up the Start of Frame flag for interrupt use in the user application.
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.
Fixed all Class drivers to ensure they have appropriate guards on each function to ensure the device is enumerated before running, fixed error codes on all guards to return "DeviceDisconnected" where possble.
Renamed HOST_SENDCONTROL_DeviceDisconnect enum value to HOST_SENDCONTROL_DeviceDisconnected to be in line with the rest of the library enum error codes.
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.
Fixed issue in AVRISP project where the target RESET line was being toggled before it was tristated, causing problems synchronising to some targets (thanks to Mike Alex).
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.
Split out common defines/types from class drivers into a seperate common class driver directory.
Make central USB Class driver dispatch headers, used for both device and host modes.
