You only hear of the failures here, thats what the forum is about. If
you think of the thousands of K3 and the many upgrades that have been
done on each the failures posted here are a small fraction of a
percentage compared to the successfull upgrades. Those that have
problems get it going based on advice here or from the great support
from Elecraft.
I too use a "real" serial port and have never had issues. I only
have the K3 conected when upgrading and turn off any virtual serial port
emulatiors before an upgrade/downgrade. that said if you are using a
USB to serial and it is working fine with the K3 for normal use I am
sure it will be fine.
As a caution I don't do it the day of a contest or when I plan to play
marathon DX. If you Brick the K3 you can reset it and try again
then restore the configuration that you backed up before the upgrade.
I have never had to do that. If you have a failure post here and the
answer to your woes will be most often answered in quick time.
in other words don't worry about doing upgrades. They will work fine
as long as you take the appropriate precautions

I have extensive notes on every setting I have ever tried/tried and
kept on the K3. The information is at hand - if needed. I also have
real serial ports on my computer - an inexpensive sure-fix elimination
of the USB converter problem. That said, with all the problems I see
here - it does not encourage me to upgrade the firmware.
I wonder what percentage of K3 owners do firmware upgrades with no
problem - compared to those having difficulties.
