The problem is that the ft2232_init() fn will invoke
jtag_xxx() fn's.
However, until ft2232_init() returns, the interface is
not set up and that part of the API is not "open for business",
causing strange effects.
ft2232_init() sets up a "default speed". We have been talking
about making JTAG speed something that the user *has to*
set up for JTAG chain validation to work and do away with the
entire concept of a "default speed".
Perhaps make 100kHz the default speed(invoked
after interface init is completed) and delete code
from driver _init() code to try to set up JTAG speed?

Hi Øyvind,
thanks for the explanation.
So, what is the suggested usage? Maybe using jtag_khz or adapter_khz in
configuration files?
regards
