Views Sub tab on user account page
Under Page settings, in the view settings, you will find the Menu option; you need to set it to:


Menu tab for user/%/content
Default menu tab for user/%/content/published
Menu tab for user/%/content/unpublished



  


This is how it appears.

PS

I used the Tracker view that comes with the Views module, and altered it to obtain the desired result.
