Connecting the NI USB-6008/6009 to a Computer
Plug one end of the USB cable into the NI USB-6008/6009 and the other 
end into an available USB port on the computer.
LED Indicator
The NI USB-6008/6009 device has a green LED next to the USB 
connector. The LED indicator indicates device status, as listed in Table 3
When the device is connected to a USB port, the LED blinks steadily to 
indicate that the device is initialized and is receiving power from the 
connection.
If the LED is not blinking, it may mean that the device is not initialized or 
the computer is in standby mode. In order for the device to be recognized, 
the device must be connected to a computer that has NI-DAQmx installed 
on it. If your device is not blinking, make sure your computer has the latest 
version of NI-DAQmx installed on it, and the computer is not in standby 
mode.
