Added new USB_GetHIDReportSize() function to the HID report parser to retrieve the size of a given report by its ID.

More additions to the unfinished HID Host Class Driver.

Add StillImage Host Class Driver functions for opening and closing sessions. Ensure IsActive is set on the interface to allow device functions to run.

Fix spelling of "Received" in all source files where it is misspelt "Recieved".

Added documentation for the constants and enums of the new StillImage Host Class driver added to the library so far.

Fixed StillImageHost not correctly freezing and unfreezing data pipes while waiting for a response block header.

Added basic PIMA commands to the StillImage Host Class driver - need to extend to PIMA specific command functions.

Re-enabled building of the Host mode demos ClassDriver directory.

Added new "Common" section to the class drivers, to hold all mode-independant definitions for clarity.

Moved SCSI command/sense constants into the Mass Storage Class driver, instead of the user-code.

Add SCSICodes.h to the Class Driver Common folder, and automatically include it in both the Host and Device Mass Storage Class drivers. Delete existing version from the ClassDriver MassStorage device demo's /Lib/ folder.

Fixed swapped paremeters in the HID state memory copy call while processing a HID PUSH item in the HID report parser.

Fixed memory corruption HID report parser when too many COLLECTION or PUSH items were processed.

Make RNDIS device class driver include the CDC device class driver header, so that it can inherrit the required CDC functional descriptor macro.

Make HID host class driver include the HID report parser.

Fix redefinition warning when USB_DEVICE_ONLY is set on an AVR which does not support USB host mode.

Added parameter directions to function parameter documentation.

Added new experimental FAST_STREAM_FUNCTIONS compile time option to speed up stream transfers at the expense of a higher FLASH consumption (needs testing to verify improved throughput).

Break device mode class driver interfaces into seperate config and state structs which are then combined, for clarity. Move device mode class driver interfaces back into the device mode class driver headers from the common class headers to make room for host class interfaces.

Change MIDI demos to use real MIDI command values, and shift for the USB wrapper, rather than shift for the MIDI bytes. This is a little confusing for the MIDI USB wrapper, but allows for the use of real standardized MIDI command values.

Remove ConfigDescriptor.c/.h files from the ClassDriver Host demos, as they will be obsoleted when the Host mode class drivers are complete. Add new StillImage stub class driver common header.

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.
