    • 8 bits of data
    • No parity

         -- SAMxxxxx-xx
         -- Compiled: xxx xx xxxx xx:xx:xx --
    
  5. When connecting USB cable to windows, the new "xxx USB Device" appears in the hardware device list.
  6. Once the device is connected and configured on windows XP, "USB Video Device" will appear in "My Computer", you can double click it to preview with default resolution - QVGA.
