Altered the Mass Storage Host LowLevel demo so that SCSI data STALLs from the attached device can be recovered from automatically without having to reset the Mass Storage interface.
Updated MS_Host_ResetMSInterface() to now perform a full Mass Storage reset sequence to prevent data corruption in the event of a device lock up or timeout (thanks to David Lyons).
Add parenthesis around the library Endianness macros that do nothing on a particular architecture to prevent operator precedence issues depending on usage.
Minor documentation corrections.
Added new USB_Host_ConfigurationNumber global variable to indicate the selected configuration in an attached device.
Renamed global state variables that are specific to a certain USB mode to clearly indicate which mode the variable relates to, by changing the USB_* prefix to USB_Device_* or USB_Host_*.
Removed the HOST_STATE_WaitForDeviceRemoval and HOST_STATE_Suspended host state machine states, as these are no longer required.
Altered the USB_Host_SetDeviceConfiguration() function to update the new USB_Host_ConfigurationNumber global as required.
Moved out the Host mode standard request convenience/helper functions from the architecture specific Host driver files to the architecture agnostic HostStandardReq.c driver file.
Fix errors in the new Audio Host mode Class Driver, which would have prevented data from being sent or received properly by the device.
Add microphone/square wave generation compile time switch to the Low Level AudioOutput Host demo.
Modified the Class Driver AudioInput and AudioOutput demos to support multiple sample rates.
Fixed KeyboardHost and KeyboardHostWithParser demos displaying incorrect values when numerical keys were pressed.
Fix broken LowLevel audio demo descriptors.
Minor documentation fixes.
Renamed all low level Pipe_Read_*, Pipe_Write_* and Pipe_Discard_* functions to use the number of bits instead of a symbolic size (Byte, Word, DWord) so that the function names are applicable and correct across all architectures.
Renamed the Serial byte send/receive functions to remain consistent with the CDC driver's byte functions.
Altered the serial byte receive function to make it non-blocking.
Added new Endpoint_Null_Stream() and Pipe_Null_stream() functions.
Removed the NO_STREAM_CALLBACKS compile time option due to the new partial stream transfer feature replacing it.
Fixed errors in the incomplete Test and Measurement device demo preventing proper operation (thanks to Pavel Plotnikov).
Change over all low level host mode project's descriptor comparator routines to perform the descriptor casting in a temp variable to make the code clearer and easier to modify (despite being more verbose).
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.
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.
