Ubuntu 9.10 maps the OpenDCC USB out of the box:

Add following section into /System/Library/Extensions/FTDIUSBSerialDriver.kext/Contents/Info.plist

                <key>USB-IF OpenDCC V1.2</key>
                <dict>
                        <key>CFBundleIdentifier</key>
                        <string>com.FTDI.driver.FTDIUSBSerialDriver</string>
                        <key>IOClass</key>
                        <string>FTDIUSBSerialDriver</string>
                        <key>IOProviderClass</key>
                        <string>IOUSBInterface</string>
                        <key>bConfigurationValue</key>
                        <integer>1</integer>
                        <key>bInterfaceNumber</key>
                        <integer>0</integer>
                        <key>idProduct</key>
                        <integer>49112</integer>
                        <key>idVendor</key>
                        <integer>1027</integer>
                </dict>

Reload kernel extension:

sudo kextload /System/Library/Extensions/FTDIUSBSerialDriver.kext

The device:

ls -l /dev/tty.*
crw-rw-rw-  1 root  wheel   11,   6 19 Mär 10:26 /dev/tty.usbserial-FTT1Y40V

The cache must be updated for the modified Info.plist.
The easiest way to accomplish this is to reboot OS X in Safe Mode:

• Hold down the shift key until the Apple Logo appears. This takes some time.
• Reboot again, in normal mode, when the Login dialog appears.
