The FTDI_Ser.dmg file was created from the file:
http://www.ftdichip.com/Drivers/VCP/MacOSX/FTDIUSBSerialDriver_v2_2_16.dmg

I modified the archive by:
1) copying it to a read/write version using Disk Utility
2) mounting it and running the 'do_patch.sh' script in this folder
   (this adds the BeagleBone A3/A4 VID/PID)
3) copying it all back to compressed version using Disk Utility

I found the file on this page:
http://www.ftdichip.com/Drivers/VCP.htm
