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.

Fix HID parser documentation for the default maximum report/path/etc. elements so that it matches the current code values.

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

Better fix to avoid void pointer arithmetic in ConfigDescriptor.h to regain C++ compatibility (thanks to Michael Hennebry).

Remove void* arithmetic in the USB_GetNextDescriptor() static inline function, to make the header file C++ compatible once again. Implement workaround for an obscure GCC bug which can cause incorrect code generation under some circumstances when the void* is re-cast.

Small tweaks to ConfigDescriptor.c/.h to ensure pointers use the correct type, and to remove const attribute from the descriptor comparator callback function pointer type define, and into the function prototype instead.

The EEPROM stream read/write functions now use eeprom_update_byte() instead of eeprom_write_byte(), so that only changed bytes are written to EEPROM to preserve its lifespan.

Changed over the AVRISP-MKII and TemperatureDataLogger projects to use eeprom_update_byte() when writing non-volatile parameters to EEPROM to preserve its lifespan.

Remove incorrect check for the current device state in the Set Configuration request handler of DevChapter9, which broke Set Configuration requests to the device under most circumstances.

Move out the SPI prescaler list to a PROGMEM module-level variable in ISPTarget.c.

Fixed possible device lockup when INTERRUPT_CONTROL_ENDPOINT is enabled and the control endpoint is not properly selected when the ISR completes.

Fix nasty bug in USBInterrupt.c which would cause a lockup if the control endpoint was not selected at the point the USB endpoint interrupt fires when INTERRUPT_CONTROL_ENDPOINT is defined.

Add new ReportType parameter to the HID class driver device callback and host report sending routines.

Renamed internal Host mode Class driver descriptor comparator callback routines so that they all start with a uniform DCOMP_{Class Abbreviation}_ prefix.

Add svn:eol-style property to source files, so that the line endings are correctly converted to the target system's native end of line style.

Device mode class driver callbacks are now fired before the control request status stage is sent to prevent the host from timing out if another request is immediately fired and the device has a lengthy callback routine.

Inlined currently unused MIDI ProcessControlRequest routine.

Added new EVENT_CDC_Device_BreakSent() event and CDC_Host_SendBreak() function to the Device and Host CDC Class drivers.

Ensure that the CDC class drivers return 0 if the number of unread bytes is queried and the bank has become empty.

Fixed INTERRUPT_CONTROL_ENDPOINT compile time option preventing other interrupts from occuring while the control endpoint request is being processed, causing possible lockups if a USB interrupt occurs during a transfer.

Fixed Host mode HID class driver not sending the correct report type when HID_Host_SendReportByID() was called and the HID_HOST_BOOT_PROTOCOL_ONLY compile time option is set.

Fixed Set Configuration requests not being stalled until the host has set the device's address.

Fixed possibility of internal signature retrieval being corrupted if an interrupt occurs during a signature byte read (thanks to Andrei Krainev).

Added new ENDPOINT_*_BusSuspended error code to the Endpoint function, so that the stream functions early-abort if the bus is suspended before or during a transfer.

The Audio_Device_IsSampleReceived() and Audio_Device_IsReadyForNextSample() functions are now inline, to reduce overhead.

Use puts_P() and printf_P() instead of the normal variants where possible in the Host mode Class Driver demos.

Oops - relocated USBInterrupt.h header file requires adjusted include paths for the other USB driver header files.

Relocate USBInterrupt.c/.h from the HighLevel USB driver directory to the LowLevel directory as it is hardware-dependent.

USB_Init() no longer calls sei() to enable global interrupts - this must now be done in the user application once all init code has run.

Fixed HID Device Class Driver not allocating a temporary buffer when the host requests a report via the control endpoint and the user has set the PrevReportINBuffer driver configuration element to NULL (thanks to Lars Noschinski).

Clean up incomplete BluetoothHost debugging commands to use GCC extension to avoid NULL parameters when no formatting is required.
