[usb] Setup token



Hi,

   During an enumeration process, what should be the address value in 
   the Setup Token. Is it always "zero" or the address value of the device
   which is being sent in "Set Address" command in the data phase?

   SetUp Token (Sync,Pid,Addr,Endp,crc5,Eop) ; Addr = 0 /  [1-128] ?
   Data            (Sync,Pid,Data0,crc16,Eop);  // Data0 has the command

   If I change the address of a device, what is the address value in the
   Setup Token. Is it zero or the old value?

   A quick reply is appreciated.

   Thanks
   Govind
