[beagleboard] Can't connect to USB serial port (FTDI module isn't loaded, ttyUSB device isn't created)

Just so you know. There is no FTDI part on the BeagleBone Black. There are no FTDI drivers to install.

If you have an USB to TTL FTDI cable plugged into a USB port and the other end plugged into the 6 pin header on the BeagleBoard Black, then that should work.
