Increase timeout of Mass Storage and Still Image host commands to 10 seconds (up from 5) to account for slow-processing devices.

Added brace guards to macros with parameters to prevent unintended changed evaluation of the macro expression.

Minor code cleanups (remove redundant comments, fix spacing, etc.).

Make sure that USB_STREAM_TIMEOUT_MS is set in the MassStorageHost ClassDriver demo, so that slow devices don't time out the data pipe. Increase pipe timeout in both MassStorageHost demos to 5 seconds to account for the really slow devices.

Fix TeensyHID bootloader not properly shutting down the USB interface to trigger a disconnection on the host before resetting the AVR.

Fixed Mass Storage Host Class driver and Low Level demo not clearing the error condition if an attached device returns a STALL to a GET MAX LUN request (thanks to Martin Luxen).

Fixed HID Parser not distributing the Usage Min and Usage Max values across an array of report items.

Added new HID_ALIGN_DATA() macro to return the pre-retrieved value of a HID report item, left-aligned to a given datatype.

Added new PreviousValue to the HID Report Parser report item structure, for easy monitoring of previous report item values.

Added CDC_Host_Flush() function to the CDC Host Class driver to flush sent data to the attached device.

Better checking of whether a packet is received in the RNDISEthernetHost Class driver demo - show busy LED status while packets are being printed out.

Make the RNDISEthernetHost Class driver demo print out incomming packets from the attached RNDIS device.

Make MIDI device demos also turn off the on board LEDs if MIDI Note On messages are sent with a velocity of zero, which some devices use instead of Note Off messages (thanks to Robin Green).

Fixed all Class drivers to ensure they have appropriate guards on each function to ensure the device is enumerated before running, fixed error codes on all guards to return "DeviceDisconnected" where possble.

Renamed HOST_SENDCONTROL_DeviceDisconnect enum value to HOST_SENDCONTROL_DeviceDisconnected to be in line with the rest of the library enum error codes.

Added new RNDISHost Host LowLevel demo. Fixed misnamed Pipe_SetPipeToken() macro for setting a pipe's direction. Fixed CDCHost failing on devices with bidirectional endpoints.

Make the StandaloneProgrammer project seamlessly read out drive contents from either an attached FAT formatted drive when in host mode, or the onboard FAT formatted dataflash when in device mode.

Added new ReportType parameter to the HID Device Class driver CALLBACK_HID_Device_CreateHIDReport() callback to indicate the report type to generate.

Fixed incorrect values for REPORT_ITEM_TYPE_* enum values causing corrupt data in the HID Host Parser.

The incomplete StandaloneProgrammer project now uses Host and Device Mass storage classes, so that program data can either be loaded onto the device's Dataflash storage, or read off an attached USB memory stick.

The USB target family and allowable USB mode tokens are now public and documented (USB_CAN_BE_*, USB_SERIES_*_AVR).

The SCSI_Request_Sense_Response_t and SCSI_Inquiry_Response_t type defines are now part of the Mass Storage Class driver common defines, rather than being defined in the Host mode Class driver section only.

The USB_MODE_HOST token is now defined even when host mode is not available.

Added missing CDC_Host_CreateBlockingStream() function code to the CDC Host Class driver.

Removed code to zero reports between two keyboard reports with differing number of pressed keys, as this relied on non-standard OS behaviour.

Fixed Endpoint_Write_Control_Stream_* functions not sending a terminating IN when the given data length is zero.

Fixed LowLevel Keyboard demo not saving the issued report only after it has been written to the endpoint.

Added support for multiple keyboard keycodes in a single report to the LowLevel and ClassDriver Keyboard demos.

Fix doxygen documentation - doxygen was getting confused on the variable-length ATTR_NON_NULL_PTR_ARG() macro used on  function prototypes and was generating many return types for several functions in the documentation (thanks to David Lyons).

Add new (incomplete) StandaloneProgrammer project, using the ELM Petite FAT library to read files stored on the board's dataflash by the host.

Change device demos which use the joystick to use the natural UP, DOWN, LEFT, RIGHT ordering in all demos when checking the joystick's position.

Corrected the name of the misnamed USB_GetDeviceConfigDescriptor() function to USB_Host_GetDeviceConfigDescriptor().

Extend incomplete RNDISHost demo -- can not enumerate a RNDIS device correctly and set the packet filter. No packets are received yet from the test device, need to investigate additional SET commands to see if any critical OIDs have been missed.

Added new stream creation function to the CDC Class drivers, to easily make standard streams from CDC Class driver instances.

Make Mass Storage device Class driver accept resets at any time, rather than just after a command block has been processed.

Remove the HID device parser from the boot protocol Keyboard/Mouse demos.

Remove dependancies from the LowLevel demos to the ClassDriver demos, since the use of ClassDriver headers now outputs an error when NO_STREAM_CALLBACKS is used.

Make Low Level host demos use void pointers for the configuration descriptor, to prevent warnings when passed to the altered configuration descriptor parsing routines.

Added preprocessor checks to give a human readable error when the class drivers are used when the incompatible NO_STREAM_CALLBACKS compile time option is used.

Descriptor processing routines now pass around void pointers rather than uint8_t pointers, as their destination datatype is know well known -- they are just streams of bytes until they are cast to the correct destination type by DESCRIPTOR_CAST.
