[video included] WD15 shuts off itself. Need to power cycle the dock to make it work again.

Every morning, the same behavior happens.

I wake my computer from sleep. At the Window login prompt, I connect the WD15 with my laptop (Dell Latitute 5580). The connection establishes (the attached monitor turn on and works). After 5-10 seconds, the WD15 shuts down on it own. The white led on the dock (and on the cable) shuts off. I have to disconnect the power of the dock, disconnect the dock from the laptop and finally reconnect the power to turn on the dock. When the white led are back, I reconnect the WD15 to my laptop and now, the connection is stable (does not disconnect) and everything works.

Is this a known issue ? How can I fix this ?
