Very cool that modern uftdi can disable JATG port not to be grabbed by ucom it
was not there back then. From my initial report it seems it was working as ucom
then jtag then ucom then jtag.. so

I modified driver directly, recompiled it, reloaded it and then tried to do the
experiment again (no reboots needed):

Cool, so you made JTAG part skip on you interface too, how? Did you modify a
driver or used devd? :-)
There were closed source drivers (libftd2xx?) that had better performance back
then and so

Thanks for the links!
Kludging uftdi driver resulted in skipping creating the interface for JTAG part
but the problem persists:

Yup that seems to be the problem. I would try to exclude "JTAG" interface from
being a

I have 2 interfaces after connecting FTDI: /dev/cuaU0 and /dev/cuaU1.
There are no other USB UARTs connected nor UART sessions (cu will exit when
device disappears).
