Wes does that mean ps4?

Wanted to turn on ps4 and trzd it goes net. Plugged in controller and then started ps4 but still does not work

It's not because your controller is empty, you have to charge it

There's the USB memory device is not connected

There's only that you should connect your controller via USB cable.
And nothing from a storage device as you wrote it in a different answer than comment.

Then please again.

It says "Learn to use a camera properly or at least to pay attention to the appropriate image orientation."…

Okay, but now to the actual answer: It says: "Connect the / a controller with a (suitable) USB cable to the PS4 and then press (on the controller) the s.g. PS button."

Some people just have to ask questions because they can't read properly.
The comment proves everything.
