Mac OS X Lion – USB TTY connector

To get a USB to TTY connector working on Mac OS X you need some information in advance.

First of all you need to know the chip that is used. I used a little workaround to get this figured out. I started my Ubuntu virtual machine connected the cable and did a “lsusb”.

icinga@icinga-dist:~$ lsusb
Bus 002 Device 002: ID 0403:6001 Future Technology Devices International, Ltd FT232 USB-Serial (UART) IC
Bus 002 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 001 Device 002: ID 203a:fff9  
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
icinga@icinga-dist:~$

With this information I googled the corresponding driver for MAC.

To get this converter working download the Mac OS X file and install: FTDIUSBSerialDriver_10_4_10_5_10_6.mpkgA

After a reboot the driver is activated. Now, if you connect your converter you will see additional devices in /dev:

ls -1 /dev/tty.*
/dev/tty.Bluetooth-Modem
/dev/tty.Bluetooth-PDA-Sync
/dev/tty.usbserial-FTDFDSPJ

The tty.usbserial-FTDFDSPJ is now your converter.

To get connected to a Cisco Router e.g. you need a serial terminal tool. I prefer minicom.

Start minicom the first time as root with:

cd /opt/minicom/2.2/bin
sudo ./minicom -s

Modify your serial port setup:

A - /dev/tty.usbserial-FTDFDSPJ
E - 98008N1

Save setup as ...
--> cisco

now start your minicom as user:

cd /opt/minicom/2.2/bin
sudo ./minicom cisco
