Fixed USB_Host_ClearPipeStall() incorrectly attempting to determine the endpoint's direction from the currently selected pipe.

Rename internal suspend and wake up USB interrupt macros so that they follow the same naming scheme as the other USB ISR macros.

Make device mode configure the control endpoint even before the bus has been reset, so that the device will enumerate correctly on hosts that do not reset the device before initial use.

More simplifications to USBController.c, fix errors and warnings when compiled for the series 2 USB AVRs.

Make USBInterrupt.c process all pending USB host mode interrupts before resetting the bus, so that no interrupts are lost when in UID auto-selection mode.

Minor documentation fixes.

Fix broken USB host mode due to the USB frame counter not being updated during the early enumeration steps, causing USB_Host_DelayMS() to spinloop forever.

Removed the EVENT_USB_InitFailure() event, as not specifying a USB mode to USB_Init() now defaults the controller into UID selection mode.

Fixed SET FEATURE and CLEAR FEATURE control requests directed at an unconfigured endpoint causing request timeouts.

Must save and restore the endpoint/pipe interrupt enable flags during reconfiguration of all endpoints/pipes in the Endpoint_ConfigureEndpoint() and Pipe_ConfigurePipe() routines.

Fix bug in Pipe_ConfigurePipe() breaking already configured pipes that was accidentally clearing the pipe's IN mode.

Added new USB_Device_GetFrameNumber() and USB_Host_GetFrameNumber() functions to retrieve the current USB frame number.

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.

Reduced HOST_DEVICE_SETTLE_DELAY_MS to 1000ms down from 1500ms to improve device compatibility while in USB Host mode, as some devices will drop off the USB bus if no connection is made within a timeout period.

Added board hardware driver support for the Olimex AVR-USB-162 development board (thanks to Steve Fawcett).

Changed the signature of the CALLBACK_USB_GetDescriptor() callback function so that the descriptor pointer is const, to remove the need for extra casting inside the callback (thanks to Jonathan Kollasch).

Optimise Endpoint_ConfigureEndpoint_Prv() function to produce smaller code when CONTROL_ONLY_DEVICE compile time token is defined.

Split out endpoint and pipe stream functions into new EndpointStream.c/.h and PipeStream.c/.h files.

Added compile time error to the AVRISP-MKII project when built for the U4 chips, as the default VTARGET detection ADC channel does not exist on these chips (thanks to Marco).

Fixed critical pipe/endpoint memory allocation issue where the bank memory address space could be silently overlapped in the USB controller if the endpoints or pipes were allocated in anything other than ascending order (thanks to Martin Degelsegger).

Removed complicated logic for the Endpoint_ConfigureEndpoint() function to use inlined or function called versions depending of if the given bank size is a compile time constant, as the compiler does a better job of optimizing with basic code.

Changed over all device demos to use a clearer algorithm for the configuring of the application's endpoints.

More spell checking of all source files -- correct missed errors, switch to EN-GB spelling dictionary.

Use static inline intermediatary functions in Endpoint.h to handle the masking for the private endpoint configuration routine, instead of performing the masking in the Endpoint_ConfigureEndpoint() macro.

Move over message ID specific header data to unions inside the standard TMC header structure, so that all header data is read in one chunk in the incomplete TMC demo.

Convert over internal pseudo-function macros to true inline functions for added type-safety and compile-checking.

Indent core library function parameters so that there is only one parameter per line, to increase readability.

Move and rename DevChaper9.c/.h and HostChapter9.c/.h to the HighLevel directory, new named DeviceStandardReq.c/.h and HostStandardReq.c/.h.

Rename LowLevel.c/.h to USBController.c/.h.

Remove dependancies on the complete <avr/io.h> header in the HighLevel USB driver directory, to ensure less work is required in later (possible) ports.

Removed the automated checking of event names in the demo, project and bootloader makefiles due to inconsistancies between the behaviour of the command line tools used to perform the check on each platform.

Removed the internal endpoint and pipe memory allocation macros, as this is already performed directly in the code. Simplify the endpoint and pipe reset procedure.

Added new Drivers/USB/LowLevel/Device.c file to house Device mode specific functions that are more complicated than simple macros. Moved USB_Device_SendRemoteWakeup() to the new Device.c source file and corrected it to unfreeze and restart the USB controller clock before issuing a Remote Wakeup request.

Removed the USB_Device_IsRemoteWakeupSent() and USB_Device_IsUSBSuspended() macros, as they are now obsolete.

Minor tweaks to the library documentation.

Spell check code and manual pages. Remove custom Doxygen CSS stylesheet, as the new 1.7 Doxygen's default stylesheet is much better.

Speed up calls to Pipe_IsPipeBound() by immediately skipping unconfigured pipes, rather than performing token check first.
