"The connected usb device isnt supported" issue

"The connected usb device isnt supported" has been stuck in my Samsung M31 notification lately though i have no usb connected...

When i tried restarting and going into safe mode it was removed for sometime but it popped up again later after charging my phone.....

My s22+ doesn't have that option. I  am trying to get my corded headphones working but it has the usb device is not supported message.

Just clean the charger port in the phone with a clean brush
