Just to sum up the discussion, is this ok for PDAs representation in HAL?:

1) Only USB-connected PDAs should appear in HAL device list, not those 
connected via serial/Ir/Bluetooth;

2) All the PDA-specific properties are merged in the device node of the 
USB device that represents the PDA in the system, no child device node 
for PDA should be created

comments, objections?

cheers,
Andrei
