07/10/2009  USBX generic code version 5.3. This release includes the following 
            modifications:

            ux_api.h                                    Changed to included new memory alignment values and TraceX events and objects,
                                                        and changed timeout value for control transfers from 1 second to 5 seconds
                                                        as some devices need a bit more time to reply to the first control request.
            ux_device_class_rndis.h                     Added a mutex to protect queuing/dequeuing of packets between the application and the RNDIS xmit thread.
            ux_host_class_storage.h                     Ensure the SCSI CBW and CSW buffers are aligned on 32bit and do not rely on the compiler packing pragma
                                                        some DMA engines of certain OHCI controllers (SH7727 in particular) requires all OHCI data buffers
                                                        to be aligned on 32 bits even though OHCI does not demand it. 
            ux_dcd_at91_transfer_callback.c             Fixed missing update of actual_length field on out transmission, and added support for Control Out 
                                                        data payload in the Atmel AT91 controller.
            ux_dcd_at91_transfer_request.c              Fixed missing update of actual_length field on out transmission.
            ux_device_class_rndis_bulkin_thread.c       Added a mutex to protect queuing/dequeuing of packets between the application and the RNDIS xmit thread, and
                                                        fixed problem when dequeuing multiple NetX packets to be sent.
            ux_device_class_rndis_initialize.c          Added a mutex to protect queuing/dequeuing of packets between the application and the RNDIS xmit thread.
            ux_device_class_rndis_write.c               Added a mutex to protect queuing/dequeuing of packets between the application and the RNDIS xmit thread.
            ux_hcd_ehci_asynch_td_process.c             Update the ux_ehci_ed_first_td field with the next td to allow USB transactions of more than 16 spanning 
                                                        multiple SOFs, and only look for transfer errors if the Halt bit of the QTD is set.
            ux_hcd_ehci_interrupt_endpoint_create.c     Filter for interval 1 when we anchor on the last ed in the tree.
            ux_hcd_ehci_interrupt_endpoint_destroy.c    Check for the forward link of the QED and ensure it is not NUL before attaching the previous QED.
            ux_hcd_ehci_request_interrupt_transfer.c    Check for no QTD allocation.
            ux_hcd_ehci_transfer_abort.c                Fixed a bug when cleaning TDs after an abort.
            ux_hcd_isp1161_interrupt_endpoint_create.c  Filter for interval 1 when we anchor on the last ed in the tree.
            ux_hcd_ohci_interrupt_endpoint_create.c     Filter for interval 1 when we anchor on the last ed in the tree.
            ux_hcd_pic32_interrupt_endpoint_create.c    Filter for interval 1 when we anchor on the last ed in the tree.
            ux_hcd_sh2a_interrupt_endpoint_create.c     Filter for interval 1 when we anchor on the last ed in the tree.
            ux_host_stack_device_resources_free.c       Filter for no interface attached to a configuration before reading the current alternate setting, which 
                                                        would cause a crash in systems where reading from address 0 is illegal.
            ux_host_stack_endpoint_instance_delete.c    Filter for physical endpoint allocation when freeing device resources.                                                        
            ux_utility_memory_allocate.c                Allow safe alignment of DMA memory for controllers which do not support scatter/gather memory - the field 
                                                        UX_ENFORCE_SAFE_ALIGNMENT needs to be defined otherwise alignment defaults to the default.

            ux_device_class_cdc.h                       Updated CDC parameter typedef, removed unused function prototypes,
                                                        and added new function prototypes.
            ux_device_class_cdc_activate.c              Added logic to call application's activate function if present.
            ux_device_class_cdc_deactivate.c            Added logic to call application's deactivate function if present.
            ux_device_class_cdc_control_request.c       Removed setup of complete function callback.
            ux_device_class_dpump.h                     Added data pump class structure, and added read/write APIs.

            ux_device_stack_control_request_process.c   Removed the verification for length in control_request_process 
                                                        due to a new mechanism to allow control request with OUT data 
                                                        payload.

                                                        now a bit per root hub port to indicate device insertion/extraction.

                                                        semaphore properly.

            ux_host_stack_rh_device_insertion.c         Changed the mechanism to report root hub port changes. There is 
                                                        now a bit per root hub port to indicate device insertion/extraction.
            ux_host_stack_transfer_request.c            Added the UX_TRANSFER_STATUS_PENDING flag to transfer request status 
                                                        when a urb is scheduled. This allows each class to ensure no urbs are
