Laptop (Windows 10) does not find MP3 player (Intenso)?

My girlfriend has a new MP3 player, but it is not recognized on her laptop, it is not even displayed anywhere. Could not find it in Device Manager or Disk Management (cmpmgmt.msc).

Have tried several USB slots and the player several times and unplugged.

The player works and is on, the cable is new.

Does anyone have an idea? Although there are many threads on the subject, but the solutions always refer to the fact that the player is not recognized, but at least displayed.

Sry, if that sounds stupid, but did you turn on the MP3 player?

(Many forget that 😂)

Yes, the player was on.
