Making endnotes clickable links with hyperref

Question

I would like to use the endnotes package, hyperref and biblatex together to have links to my endnotes. Here is a MWE that shows how the links don't show up:

\begin{filecontents}{testbib.bib}
@Book{jones00,
  author =   {Douglas Jones},
  title =    {A book},
  publisher =    {The metasyntactic variable publishing company},
  year =     2000}
\end{filecontents}

\documentclass{article}
\usepackage{endnotes}
\usepackage[autocite=footnote,notetype=endonly,style=verbose-trad1]{biblatex}
\bibliography{testbib}
\let\footnote\endnote
\usepackage{hyperref}
\begin{document}
Something\autocite[p.12]{jones00} something else\footnote{another endnote?}

\theendnotes
\end{document}

I'm open to other end-note producing options that work better with hyperref, but I'd rather stick with article document class.

I once uncovered the following code on comp.text.tex, credited to Ulrich Dirr:

Load it with the endnotes package (after hyperref) and enjoy.

Answer 2

It seems that this is not a biblatex issue. The hyperref README states on page 18 that the endnotes package is "[u]nsupported".
