In the meantime, my BBBlack arrived. I could not find the Adafruit cable = here in Brazil and so I ordered this FTDI to USB converter. = http://produto.mercadolivre.com.br/MLB-775084107-modulo-conversor-usb-seri= al-ft232rl-ttl-ftdi232-arduino-_JM = Its six pins are in the same order as on the BBBlack and I used the USB = cable that came with the BBB for connecting the converter and 3 short = patch cables for connecting it to the BBBlack. It is working very well.
