APU set up with Wi-Fi

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?
Just these ones:
/var/log $ ls alternatives.log auth.log.4.gz dpkg.log kern.log.2.gz pm-powersave.log.3.gz teamviewer alternatives.log.1 boot.log dpkg.log.1 kern.log.3.gz pm-powersave.log.4.gz udev alternatives.log.2.gz bootstrap.log dpkg.log.2.gz kern.log.4.gz pycentral.log ufw.log alternatives.log.3.gz btmp dpkg.log.3.gz lastlog samba unattended-upgrades alternatives.log.4.gz btmp.1 dpkg.log.4.gz mail.err speech-dispatcher upstart alternatives.log.5.gz ConsoleKit dpkg.log.5.gz mail.log syslog vbox-install.log apt cups faillog mdm syslog.1 wtmp aptitude dmesg fontconfig.log mintsystem.log syslog.2.gz wtmp.1 aptitude.1.gz dmesg.0 fsck mintUpdate.history syslog.3.gz Xorg.0.log auth.log dmesg.1.gz hp news syslog.4.gz Xorg.0.log.old auth.log.1 dmesg.2.gz installer pm-powersave.log syslog.5.gz Xorg.20.log auth.log.2.gz dmesg.3.gz kern.log pm-powersave.log.1 syslog.6.gz Xorg.20.log.old auth.log.3.gz dmesg.4.gz kern.log.1 pm-powersave.log.2.gz syslog.7.gz -
Try dmesg | grep -i usb

Results are:

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=item2587ff9abcI assume you're in Australia. :)
Try looking at the syslog in Mint:
cat /var/log/syslog|grep usbor tail it whilst you plug in the cable:
tail -f /var/log/syslogSteve

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 May 16 11:20:26 linuxmint-Z68MA-D2H-B3 kernel: [ 9232.342528] usb 2-1.2: new full-speed USB device number 3 using ehci-pci May 16 11:20:26 linuxmint-Z68MA-D2H-B3 kernel: [ 9232.436085] usb 2-1.2: New USB device found, idVendor=1a86, idProduct=7523 May 16 11:20:26 linuxmint-Z68MA-D2H-B3 kernel: [ 9232.436090] usb 2-1.2: New USB device strings: Mfr=0, Product=2, SerialNumber=0 May 16 11:20:26 linuxmint-Z68MA-D2H-B3 kernel: [ 9232.436093] usb 2-1.2: Product: USB2.0-Ser!

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

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
cu: /dev/ttyUSB0: System not found$ screen /dev/ttysUSB0 19200
[screen is terminating]
$ screen /dev/ttys0 19200
[screen is terminating]$ minicom
minicom: cannot open /dev/tty8: Permission denied$ sudo mincom
Welcome to minicom 2.6.2OPTIONS: I18n
Compiled on Feb 8 2013, 07:03:03.
Port /dev/tty8, 22:05:36Press CTRL-A Z for help on special keys
$ putty
Serial line: /dev/ttyUSB0 > Speed: 9600 > PuTTY Fatal Error: Unable to open connection to: Unable to open serial port. -
Right so you have the permissions error.
Looks like it's the 'dialout' group you need to be added to. Try doingsudo adduser your_account_name dialoutThen 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/ttyUSB0https://fedorahosted.org/fldigi/wiki/Documentation/HOWTO/Serial_Port_Setup
Steve

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.
Steve

Okay, I bought a Null Modem cable.
Plugged into APU and USB cable.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.
-
Hmm. Well you clearly have some problem there. Do you have anything else you can use to prove the serial terminal with?
Steve
-
I'm trying to think of a way of proving the serial terminal.
All I can think of is
trying another Null modem cable
trying another computer's USB port. (I tried Linux, Mac and Windows).I thought the MicroSD 8GB card might not have the pfSense OS file properly, but I understand this would not effect the serial connection needed to configure the MicroSD 8GB card?
