From the peperoni makers...

Dear Kevin
The steady blue light means - you are right - that DMX is received. In addition it means that there are not USB transactions going on. The later seems to be the reason for your problems: the catalyst software is not handling the Rodin2 anymore.
As long as the software is handling the interface the blue led is flashing with approx 2Hz. If there is no DMX signal present the led will flash red with approx 2Hz and keep signalling usb transactions in blue.
Hopefully that helps.

Kind regards
Jan Menzel

...For all you who know more about Catalyst than I do...If this is true, why would Catalyst stop handling the peperoni adapter all of it's own accord?
