Modification history
--------------------
01b,19jan05,h_k added pragma pack to USB_DESCR_TYPLEN and USB_HID_DESCR and
added USB_HID_DESCR_LEN. (SPR #104230)
01a,08sep04,ami New macros added
01a,16jul04,??? Backward compatibility with the USB 1.1 Peripheral stack
02b,03may04,??? Addition of macros for USB 2.0
02a,2April04,prashee USB 2.0 modifications
01i,28mar02,h_k removed #if (CPU==SH7700)&&(_BYTE_ORDER==_BIG_ENDIAN) and set
USB_MAX_DESCR_LEN 255 for SH7700 (SPR #73896).
01h,16nov11,wef Pack ENDPOINT_DESCRIPTOR structure.
01g,08nov11,wef add provisions for SH - pack structures and conditionally make
USB_MAX_DESCR_LEN a multiple of 4
01f,18sep01,wef merge from wrs.tor2_0.usb1_1-f for veloce
01e,25jul01,rcb fixed spr #69287
01d,26jan00,rcb Add "dataBlockSize" field to USB_IRP to give application
greater control over isochronous transfer sizes.
Change USB_BFR_LIST "bfrLen" and "actLen" fields to UINT32.
01c,12jan00,rcb Add definition for USB_CLASS_AUDIO.
Add typedef for USB_DESCR_HDR_SUBHDR.
01b,07sep99,rcb Add definition for USB_TIME_RESUME.
01a,03jun99,rcb First.
