1 . A system comprising a main device and an auxiliary device arranged to co-operate with each other, the auxiliary device being arranged to effect a core functionality, the auxiliary device comprising descriptors, characterised in that at least one descriptor defines a functionality that is different from the core functionality.  
     
     
         2 . The system according to  claim 1 , wherein the main device is a USB host and the auxiliary device is a USB device.  
     
     
         3 . The system according to  claim 2 , wherein the functionality that is different from the core functionality is a mass storage functionality.  
     
     
         4 . The system according to  claim 1 , wherein the auxiliary device, when it is coupled to the main device, initially presents the descriptor, that defines a functionality that is different from the core functionality.  
     
     
         5 . The system according to  claim 2 , wherein the USB device comprises a driver for the USB host to be installed by simulating that the USB device is a mass storage.  
     
     
         6 . The system according to  claim 2 , wherein the USB device is a smartcard.  
     
     
         7 . An-auxiliary device arranged to effect a core functionality, the auxiliary device comprising descriptors, characterised in that at least one descriptor defines a functionality that is different from the core functionality.  
     
     
         8 . The auxiliary device according to  claim 7 , wherein the auxiliary device is a USB device.
