//  Revision History:
//  $Log: $
//
//  Rev 1.02  02/22/01 Ek .Modified UnpaqAclEvent() function to handle Acl Packet Format for USB 
//                         properly by decrementing the buffer pointer by 1 Byte to make up for
//                         Uart's TPL byte.
//  Rev 1.01  12/22/00 Ek .Added UnpaqAclEvent(char* AclHeaderBuf, CString& ParamStr) function
//                         to decipher Acl Event.
//            12/18/00    .Changed CHCI_ACLDataProcessor::ParseHCI_ACLData return value from uint8
//                          to tDataParseStatus type to match with other function call
//  Rev 1.00  15 July 2000 Initial release
