I am not sure what is unclear, but the conclusion is that it is not
possible without a major board redesign which is not worth the whole hassle
for us.

Unfortunately, "of course you can" is technically wrong here. You could
only do that by modifying every single adapter for everyone. That is not
worth the hassle for us.

No, major board upgrade is not planned within the next long while, but then
again: I am just reiterating the TI thread. :-) There is no unused ftdi
controller pin, so minor upgrade would not solve this.
