Hello,
I have an OpenOCD USB dongle. It uses a FT2232D chip. The first port
implements the JTAG interface and the second port implements a standard serial
interface,
The uftdi driver recognizes both ports and I can use the second port as a
serial interface. But libftdi does not find any device, even if uftdi is not
loaded. OpenOCD relies on libftdi, so I can not use that dongle.
