Removed the ENDPOINT_DESCRIPTOR_DIR_* macros in favour of the shorter ENDPOINT_DIR_* macros, which can now be used with both Endpoint_ConfigureEndpoint() and in the device descriptors.

Move out the EP_TYPE_* macros to the base USBController.h header, as these are used in the device descriptors as well and thus must not be changed.

Remove V2 branch for now, to concentrate on a V1 implementation of the USB XMEGAs before large-scale API alterations.

Automatically load in the USB calibration bytes from the User Signature Row on start-up.

Create internal SRAM variable for the endpoint control and status register table, used by the XMEGA USB controller hardware.

Start the USB clock source generator inside USB_ResetInterface() for XMEGA devices.

Add XMEGA to the LUFA core library makefile's list of architectures, so that the XMEGA files are properly cleaned on request.

Update UC3 platform driver support to use the bitmasks defined in the header files over raw constants.

Start implementation of XMEGA platform drivers.

More XMEGA USB AVR device port work - re-add missing Endpoint stream functions, remove unnecessary internal functions.

MultiArchDemos: Correct usage of updated INTC_RegisterGroupHandler() in the ported demos.

Added Device Qualifier standard descriptor structure definitions USB_StdDescriptor_DeviceQualifier_t and USB_Descriptor_DeviceQualifier_t.

Add device support preprocessor checks and use symbolic bit names in the UC3 platform clock management driver.

Fix compile errors in the UC3 platform support due to a forward reference and an incorrect function prototype.

Remove unneeded #include of Device.h in StdDescriptors.h breaking compilation for some user projects.

Fixed error in the pipe unordered allocation algorithm for the AVR8 devices breaking compatibility with some devices.

Fix incorrect standard request name in the host standard request driver.

Fix duplicated LED driver functions in the Doxygen documentation.

Add endianness information to the class driver and core structure definitions.

Move out the unused Ethernet_Frame_Info_t structure definition to the RNDIS device demos where it is needed.

Replace blind interface descriptor search in the incomplete AndroidAccessoryHost demo with an intelligent search for the correct interface in the device matching the correct class/subclass/protocol values.

Updated all host mode demos and projects to use the EVENT_USB_Host_DeviceEnumerationComplete() event callback for device configuration instead of manual host state machine manipulations in the main application task.

Added new USB_Host_ConfigurationNumber global variable to indicate the selected configuration in an attached device.

Renamed global state variables that are specific to a certain USB mode to clearly indicate which mode the variable relates to, by changing the USB_* prefix to USB_Device_* or USB_Host_*.

Removed the HOST_STATE_WaitForDeviceRemoval and HOST_STATE_Suspended host state machine states, as these are no longer required.

Altered the USB_Host_SetDeviceConfiguration() function to update the new USB_Host_ConfigurationNumber global as required.

Moved out the Host mode standard request convenience/helper functions from the architecture specific Host driver files to the architecture agnostic HostStandardReq.c driver file.
