USB port has power but doesn't see devices or charge controllers

Hello there from the sticks somewhere in France ^^,

First time on this forum! I’ve got a PS4 Slim with one USB port working fine and another one with power (checked it with a USB port voltage meter USB stick) but no data. The port doesn’t see devices when they are plugged in and it doesn’t want to charge controllers even though it has power. Has anyone seen this issue before? What should I start checking? Thanks for you help n__n
