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.
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.
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.
Add new manual pages detailing the advantages of LUFA over the official Atmel USB AVR stack, and reasons why LUFA should be used over a built-from-scratch USB stack.
Fix KeyboardHost ClassDriver demo; boot protocol keyboard report structure in the Host Mode HID Class driver uses the full keycode array from the attached device.
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 more skeleton functions and definitions to the Mass Storage Host mode Class driver.
Made Endpoint_Write_DWord_* functions echo the structure of the matching Endpoint routines for clarity.
Added new Endpoint_SetEndpointDirection() macro to set the current endpoint direction for bidirectional endpoints.
Renamed internal USB_INT_ENDPOINT_SETUP macro to USB_INT_RXSTPI to fit in with the rest of the interrupt vector macros.
Fix corruption in Device RNDIS demos TCP stack when too many connections attempted simultaneously, freezing the device when a page was re-fetched before the first connection was closed.
Fix incorrect model compatibility information in the Host LowLevel demo overview text files.
Remove VBUS events - not needed as the library takes care of VBUS detection and feedback on supported AVRs via the USB_Device_Connected and USB_Device_Disconnected events.
Fixed incorrect Host state assignment in the incomplete BluetoothHost demo.
Fix USB_PLL_Off() call in the series 4, 6 and 7 microcontroller disconnect interrupt handler code, which wasn't guarded by a test of USB_Options to check if the user has specified manual PLL control (thanks to Brian Dickman).
Changed USB_Init() and USB_Shutdown() so that they are no longer dependant on oneanother for possible code savings when the interface is never explicitly shut down.
Added new Endpoint_ClearStatusStage() convenience function to assist with the status stages of control transfers.
Removed vague USB_IsConnected global - test USB_DeviceState or USB_HostState explicitly to gain previous functionality.
Removed USB_IsSuspended global - test USB_DeviceState against DEVICE_STATE_Suspended instead.
Fixed possible enumeration errors from spinloops which may fail to exit if the USB connection is severed before the exit condition becomes true.
Added new USE_FLASH_DESCRIPTORS compile time option. By default, descriptors can now lie in mixed memory spaces (specified by a new parameter to the CALLBACK_USB_GetDescriptor() function) unless one of the USE_*_DESCRIPTORS compile time option is specified.
