Devices Getting Started Guide that shipped with your device, and is also

The NI USB-9219 device has a green LED next to the USB connector. The
LED indicator indicates device status, as listed in Table 1. 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
