Research  : ability to identify ...and interpret devices connected to a port

example   : Both a mouse and keyboard are ps/2 compatible ...but if connected
            vice-versa ...difficult to identify the device


Opportunity :  On the lines of some wire-less protocols (say bloo-tooth) ..etc
               ability to connect ...different or multi-purpose devices ...to 
               a port and be able to service accordingly ...to be more apt the
               usb or serial ports and compatible devices in the context of computing.

               while the concept of DOS or microsoft -interrupt may sound familar
               ...but in reality ...this need to translate or portable with physical
               devices ...to be in sync with above.
              

               ...kind of standard post used in computing or embedded systems ...
               during which device identification takes place ....either by bit-flow
               in reverse direction ...or other envisible means.

             Ex: in a mobile device ...a karoke of nokia 6600 ...is identified as
                 as a head-set by nokia lower-end models ...context this was found is 
                 some nokia mobile phones while supporting ..a speaker phone ...
                 strangely require ..head-set hooked up for the FM radio to be played
                 ...while the speaker-phone could be used or switched on when reciving a call.


              Thus a standard port-type ...and multiple devices (usually dumb or non-intelligent
              in nature) that can interface with such ports in mobile computing context.


              the compatibility 'SD Card Slot' present on the mobile computing platforms
              viz. ability to port or share data between mobile-hand-helds and portable computing
              termable as desktop or laptops ....provide for features on the PCB i.e. IO descriptors
              that support read and write ....thus USB protocol and portable devices which have 
              limitations of data marshalling (56k limit) ...can be ported to this kind of interface,
              ...thus scope for USB or similar modems that can be sloted into  the SD-card slots
              that can  give better performance than pcmcia or express-slots for pcmcia ...

              for more information ...this individual...had published specifications ...limitations,
              advantages , disadvantages ...with reference to USB-protocol and usb compatible devices
              ...you find the document on this URI or URL
              
              

usages: Mobile devices ...hooking up accessories to all kinds of computing devices.
                                
 Note: The above problem statement having been encountered in various scenarios
      and detailed in various 'Proof of concepts' as mentioned in

        ....apply appropriate
      'use-case' modeling, rationalize and arrive at a workable and feasible 
       solution both commercially and techinically viable.
