hi,
    
     I have a small question on USB,   since USB is a polled bus,  the Host always 
polles the devices for interrupts.  If  I develop a User Interface on the Device side 
and allow the user to select the options on the UI  and send the user inputs via 
Interrupt transfers (As Interrupt transfers are polled by Host every 10 msec).   Is 
this feasible,  to implement.  If so,  what are the software layers to be implemented 
on Host side and on the Device side.  
 
   Please could you answer this question ASAP.
 
thanks & regards
