<p class="para block block-first">There are two ways to set up the iPod to make libgpod able to find its firewire id.
                </p>
<p class="para block">The 1st one is mostly automated. First, make sure you have libsgutils installed before running configure/autogen.sh. If you built libgpod without it, install it and run configure/make/make install. You should now have an ipod-read-sysinfo-extended tool available. Run it with the iPod device path (eg /dev/sda) and the iPod mount point (eg /media/ipod) as arguments. This may require root privileges. ipod-read-sysinfo-extended will read an XMLfile from the iPod and write it as /media/ipod/iPod_Control/Device/SysInfoExtended. See http://ipodlinux.org/Device_Information for more details about the method used.
                </p>
<p class="para block">Having that file is enough for libgpod to figure out the iPod firewire id.
                </p>
<p class="para block">The 2nd method requires more manual intervention. First, you need to get your firewire id manually. To do that, run "sudo lsusb -v | grep -i Serial" (without the "") with your iPod plugged in, this should print a 16 character long string like 00A1234567891231. For an iPod Touch, this number will be much longer than 16 characters, the firewire ID is constituted by the first 16 characters. Once you have that number, create/edit /media/ipod/iPod_Control/Device/SysInfo (if your iPod is mounted at /media/ipod). Add to that file the line below:
                </p>
<div dir="ltr" class=" block programlisting block-indent"><pre class="programlisting">FirewireGuid: 0xffffffffffffffff
                </pre></div>
<p class="para block">(replace ffffffffffffffff with the string you obtained at the previous step and don't forget the trailing 0x before the string)
                </p>
<p class="para block">Save that file, and you should be all set. Be careful when using apps which lets you manually specify which iPod model you own, they may overwrite that file when you do that. So if after doing that libgpod still seems to write invalid content to the iPod, double-check the content of that SysInfo file to make sure the FirewireGuid line you added isn't gone. If that happens, read it to the end of the file, and make sure libgpod rewrite the iPod content.
                </p>
<p class="para block">Once that is done, if you compiled libgpod from source, you can test that libgpod can find the firewire ID on your iPod by running
                </p>
<div dir="ltr" class=" block programlisting block-indent"><pre class="programlisting">libgpod/tests/test-firewire-id /ipod/mount/point
