    android: Adjust libusb download instructions
    
    Use a local manifest to download libusb just like we're doing in the rest of
    the labs.
    
    Also, both external/libusb and external/libusb-aah have to be removed to
    prevent conflicts.

 need a more recent version anyway, we will need to edit the manifest
 so that repo grabs a newer version instead.
 
-Edit the file \code{.repo/manifest.xml}. This is the manifest
-currently used by repo. As you can see, it holds the git repositories
-of every pieces assembled to form the Android source code.
-
-The first step will be to add a remote git server to the list of those
-availables to \code{repo}.

-\begin{verbatim}
-<remote fetch="git://libusb.org" name="libusb" />
-\end{verbatim}
-
-Then, go to the line that defines the libusb project, and edit it to
-specify that you want to use the remote we just defined (using the
-\code{remote} attribute), that we want to use the version 1.0.9, that
-is in git \code{refs/tags/1.0.9} (using the \code{revision} XML
-attribute), and change the value of the name attribute to
-\code{libusb}.
+Create a new local manifest to download the libusb from the git
+repository \code{git://libusb.org/libusb.git}. You'll need to use the
+version 1.0.9, that is in git \code{refs/tags/1.0.9}. You'll also need
+to remove both the existing \code{libusb} and \code{libusb_aah}
+projects from the manifests.
 
 Then, do a \code{repo sync}, and everything should be downloaded.
