It is not a trouble regarding the JTAG Frequency here.
If you ask the Amontec JTAGkey-2 to scan in/out it will scan in/out at
the frequency you provided.
If you provided a too high TCK frequency, without the RTCK enabled, the
data returned will be not correct, but will be EVER present and EVER
complete (at 30Mhz TCK frequency or at 1MHz TCK frequency ....).
The problem here is regrading the number of returned bytes, and not on
which frequency Drasko run the scan.
I am waiting on the log using the Amontec JTAGkey d2xx WHQL certified
driver . Maybe we will see something different, in this case it is a
trouble in the libftdi . If the same some trouble in the higher JTAG
level in openocd source.
