the plugable doesn't boot up

just opened my super speed 7-port usb 3.0 hub. plugged it in to electric socket and to computer but no blue lights come on, computer

Hi Bill,

Thanks for posting here! There is a blue LED for each of the downstream USB ports on the Plugable 7 Port USB 3.0 hub. The blue LEDs for each port would only light up when a USB device is connected and recognized by the operating system.

Are any devices connected to the Plugable 7 Port USB 3.0 hub?

If no devices are connected, could you connect a USB device through the Plugable 7 Port USB 3.0 hub and let us know if the blue LED did light up or not?
