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.
Moved the USB device selection logic for ENDPOINT_TOTAL_ENDPOINTS further up in Endpoint.h to where the endpoint bank capabilities are determined, to reduce the total number of device-specific logic.
Change USB_Host_WaitMS() to test and disable the HSOFI interrupt before resuming the bus, so that it does not fire before the delay loop has run.
Add missing const qualifier to the parameter of USB_Host_ClearPipeStall().
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.
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.
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.
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.
Added spacing between multiple paragraphs in Doxygen \note sections.
Removed call to the clock prescaler reset function in the Teensy bootloader to save space - the user application is accessed via a watchdog reset anyway, so the prescale reset would only affect the speed of the bootloader itself.
Mark the AVRISP-MKII project descriptors as being both Bus Powered and Device Powered.
Copy over file level documentation of the peripheral drivers to the module level documentation.
