One hint is in the README file:

  ==================
  Installing OpenOCD
  ==================

  On Linux, you may have permissions problems to address.  The best
  way to do this is to use the contrib/udev.rules file.  It probably
  belongs somewhere in /etc/udev/rules.d, but consult your operating
  system documentation to be sure.  ...

Though of course the name is now "openocd.udev" not "udev.rules"; I'll
fix that.

Try the "contrib/openocd.udev" file instead ... I use "81-openocd.rules"
instead, the difference likely doesn't matter much.

If there are differences which do matter, please submit a patch.

I'd have thought more like chapter 4 on Running OpenOCD ... chapter 8 is
about Tcl support.  I'll add a mentions in both places about the need for
OS-level setup ... chapter 4 will mention udev for Linux, and driver stuff
for MS-Windows.

However, the User's guide is not the place for OS-specific details, so
I won't add them in either place.
