Hi Nicu,

Did this ever get fixed? I've been periodically checking the changelog at
but that still only shows v1.4 released on 2012-10-24 (before the above exchange).

However, I've *just* noticed that there's a v1.5 firmware for the
OpenUPS (since 2013-09-27, in fact). Did that fix this issue? Is there
a changelog available for v1.5?

Also, since the thing is in production now, do you happen to know if it
can be flashed from Linux using https://code.google.com/p/mphidflash/
or indeed anything else?
