      Thanks for the help.

      Multimeter yellow dial set to 20V.

      Black cable pushed into the inside of the 2.5mm power supply connector (positive).
      Red cable touching the outside of the 2.5mm power supply connector (negative).
      Multimeter result: 12.1.

      Red cable pushed into the inside of the 2.5mm power supply connector (positive).
      Black cable touching the outside of the 2.5mm power supply connector (negative).
      Multimeter result: - 12.1.

      Serial female to female cable.

      Serial male to USB.

      So yes, it seems the power supply is working.
      No life at all on the APU?
      Maybe the APU needs a trick like connecting an Ethernet cable or powering up and then putting the microSD card in the APU?

        Ok, check the leads at the multimeter end. The black lead is definitely in the COM connector and the red lead in the ' VOhmmA' connector?

        Just as an aside here, I'm not sure how familiar with meters you are, do not put the red lead in the other connector, usually marked '10A', unless you know what you're doing. It's so very easy to kill powersupplies doing that!  ;)

        If the leads are correct then it looks like your power supply is wired 'centre negative' which is incorrect:

        @http://pcengines.ch/apu1c.htm:

        12V DC, about 6 to 12W depending on CPU load. Jack = 2.5 mm, center positive

        Maybe you typo'd the results? Where did you source the PSU?

          So
          the power supply cable tip had the negative cable end with the 2.5mm metal positive.
          the power supply cable tip had the positive cable end with the 2.5mm metal negative.

          I changed
          the power supply cable tip with the negative end with the 2.5mm metal negative.
          The power supply cable tip with the positive end with the 2.5mm metal positive.

          Black cable pushed into the inside of the 2.5mm power supply connector (positive).
          Red cable touching the outside of the 2.5mm power supply connector (negative).
          Multimeter result: -12.13.

          Red cable pushed into the inside of the 2.5mm power supply connector (positive).
          Black cable touching the outside of the 2.5mm power supply connector (negative).
          Multimeter result: 12.13.

          The ALU now shows a green LED light on the MOBO D7, D10 and D11.

          The computer isn't showing any recognition of a USB connection.
          My OS is Linux Mint 16 Mate 64-bit.

            You'll have to check the logs in Mint to see what it made of the cable. It could be some obscure converter chip.

              Ok, not sure how to find logs on Linux Mint 16.
              I went to /var/log, but nothing really re USBs?

              I'm wondering if the MicroSD card is causing the pfSense OS to somehow not load and 'awaken' the USB port?
              The MicroSD card has pfSense-2.1.2-RELEASE-4g-amd64-nanobsd-20140410-0542.img on it.
              I downloaded this file from pfSense download
                > Computer Architecture: AMD64 (64-bit) > Platform: Embedded (NanoBSD) typically with CF > Console: Serial > CF card size: 4GB.

                Logs are usually in the /var/log directory

                  USB logs should be in /var/log/messages

                  You can run a tail -f /var/log/messages which is a live display of the log. Or use a cat or vi command to see the log

                    Thanks for the suggestions.

                    /var/log has no directory or file names messages?

                        Maybe the memory card doesn't work?
                        I think the APU is supposed to have a Compact Flash 4GB card, but I have a MicroSD card 4GB?

                          So, just ordered a new Serial female to female adaptor, in case the current serial female to female cable is faulty.

                          I also removed the APU's microSD 8GB card > placed the microSD 8GB card into the memory card reader > placed the memory card reader into the computer's USB > opened the microSD 8GB card's folder > unzipped pfSense-2.1.2-RELEASE-4g-amd64-nanobsd.img.gz > deleted pfSense-2.1.2-RELEASE-4g-amd64-nanobsd.img.gz > kept the unzipped file pfSense-2.1.2-RELEASE-4g-amd64-nanobsd-20140410-0542.img > ejected the memory card reader > removed the microSD 8GB card from the memory card reader > placed the microSD 8GB card into the APU > powered on the APU > connected the APU into my computer's USB port > the computer is still not recognising any USB from the APU (the computer recognises other USB devices ok).

                          I also tried the APU USB cable in another computer which recognised no USB when plugged into the 2nd computer.

                            Neither that adapter or the cable you linked to earlier are null-modem cables which is what you need. Something like this:
                            http://www.ebay.com.au/itm/1-5m-Serial-RS232-Null-Modem-Cable-Female-to-Female-DB9-FTA-DB9F-F-/161195465404?pt=AU_CablesConnectors&hash=item2587ff9abc

                            I assume you're in Australia. :)

                            Try looking at the syslog in Mint:

                            cat /var/log/syslog|grep usb

                            or tail it whilst you plug in the cable:

                            tail -f /var/log/syslog

                              Thank you for the reply.

                              Forgive my ignorance, but what is the difference between the
                              null-modem cable and the
                              serial female to female cable I bought or the
                              serial female to female adaptor I bought?

                              Not quite sure what I'm looking for with the below commands.
                              I have included the output if it helps check the USB with the APU cable plugged in.

                              
$ cat /var/log/syslog | grep usb

                                A null-modem cable has the transmit and receive lines crossed such that two machines with standard serial ports can talk to one another. A standard serial cable for connecting a PC to some other serial device does not.
                                See:
                                http://en.wikipedia.org/wiki/Null_modem

                                It looks like your USB-serial adapter was recognised just fine:

                                You should be able to open ttyUSB0 in a serial terminal emulator, like putty. In Xubuntu there is an issue where the user doesn't have permissions to access the serial port and putty gives no helpful errors or log entries. Nice  ::). The workaround is to add your user to the modem group. There may be a similar issues in Mint.

                                  Oh, great to see the APU is connecting via the USB port.

                                  So, I've tried a few ways to connect to the serial APU.

                                  Terminal > $ cu -1 /dev/ttyUSB0 -s 19200

                                    Right so you have the permissions error.
                                    Looks like it's the 'dialout' group you need to be added to. Try doing

                                    sudo adduser your_account_name dialout

                                    Then logout and back in again. Try Putty again.

                                      Yes, I did the line $ sudo adduser user_name dialout.

                                      Logging gives the same results?

                                        Hmm, well that's all that's requiered in Xubuntu but Mint may be different (different versions of Mint too) but usually isn't because they're all Debian based.
                                        You may need to reboot if logging out and back in didn't do it.
                                        You may also need to do:

                                        sudo chmod a+rw /dev/ttyUSB0

                                          Thanks. Yes, I had actually tried the chmod a+rw /dev/ttyUSB0, but same errors.

                                          I tried:
                                          Terminal > $ putty > Connection type: Serial > Serial line: /dev/ttyUSB0 > Speed: 9600 > Open > Black window opens with the Title /dev/ttyUSB0 - PuTTY and green blinking cursor, but unable to type anything.

                                          Terminal > $ putty > Connection type: Serial > Serial line: /dev/ttyUSB0 > Speed: 19200 > Open > Black window opens with the Title /dev/ttyUSB0 - PuTTY and green blinking cursor, but unable to type anything.

                                          Terminal > $ putty > Connection type: Serial > Serial line: /dev/ttyUSB0 > Speed: 38400 > Open > Black window opens with the Title /dev/ttyUSB0 - PuTTY and green blinking cursor, but unable to type anything.

                                          Terminal > $ putty > Connection type: Serial > Serial line: /dev/ttyUSB0 > Speed: 115200 > Open > Black window opens with the Title /dev/ttyUSB0 - PuTTY and green blinking cursor, but unable to type anything.

                                            That is the expected behaviour if you're not connected to a serial console. Since your cable is not a null-modem you aren't seeing anything. Putty has a gui you can use to set the serial speed etc.
