Many thanks to everybody, who replied to my message.
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.

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.
Best regards
Rolf
