My apologies, I failed to include the log.
Here follows a bad run, followed by a good one.
The good one was with a 2452.
The 2001 was seen as Device ID: 0xf201, Device: MSP430G2231, exact
same when testing a 2121, and for both the FET recognition had to run
twice.
Testing was in two different Launchpads - all 3 2553 I tested failed
to be recognized/load mspdebug, all the other chips loaded/worked with
no further concerns, the 2452 (3 tested) were recognized at the first
FET identification run and worked fine.
