USB connect/Disconnect sound


I have a dell latitude E7440 which is docked. There is a regular sound of a USB connecting and disconnecting all the time. There is currently 2 USB's connected to the dock (Mouse & Keyboard) 

Any ideas/solutions there may be to this issue.

RE: USB connect/Disconnect sound


Thank you for reaching us.

Does this happens when the laptop is not docked?

Can you try using the keyboard and mouse directly with the laptop bypassing the dock.

Sometimes this issue can due to laptop webcam too which also uses USB interface to communicate with the system board.

We need to isolate the problem before resolving it.

Please respond to us in the same thread after trying out the above mentioned steps.

Thank you
