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.

Make project makefiles correctly clean intermeditary build files from assembly and C++ sources (thanks to Daniel Czigany).

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

Modified PRNT_Host_USBTask() to flush the output pipe on each call.

Added new project makefile template to the library and moved board driver stub files into in a new CodeTemplates directory.

Added LEDs_ToggleLEDs() function to several board LED drivers which were missing it (thanks to Andrei Krainev).

Simplify some of the LED driver functions to produce more compact code.

Added new PRNT_Host_BytesReceived() and PRNT_Host_ReceiveByte() functions to the Print Host Class driver.

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).

Clarify in the project documentation files what the each of the different USB AVR device "series" comprises of.

Fix incorrect ADC driver documentation for the parameters of ADC_Init(), fix incorrect call to ADC_Init() in the TemperatureDatalogger project.

Fix up documentation - remove obsolete Scheduler Overview page, roll documentation into the documentation for the (deprecated) Simple Scheduler module.

Remove remaining void* descriptor casts in the projects and demos that were not removed when the GetDescriptor callback function's signature was altered.

Fixed LowLevel PrinterHost demo not sending control requests to the attached printer with the correct printer interface wIndex value.

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.

Changed all Device mode LowLevel demos and Device Class drivers so that the control request is acknowledged and any data transferred as quickly as possible without any processing inbetween sections, so that long callbacks or event handlers will not break communications with the host by exceeding the maximum control request stage timeout period.

Moved calls to Device mode Class Driver events to after the request has been acknowledged, so that long event handlers do do skew the timing of the control requests.


Fixed USBtoSerial and Benito project SetLineEncoding calls failing if the USART is busy, due to the RX ISR delaying the control request handler.
