turned out to be something like that. It works fine on a different computer
with a different cable. I haven't further investigated the issue so I can't
tell if it was the usb interface on my pc or the cabeling..

I have an early mini-module and experience the same failure with different cables. I have never had any issues with the interface (that I am aware of)

bash-3.2$ ./jtag-ft2232h  -c
[***] my_ftdi_read_data gives up polling.
IO Error: FTDI/USB read failed!
