2 things I can think of.

First, you may need to run the Zadig again.  I found that sometimes when I unplugged mine it would "see" it again unless I reinstalled the drivers. Second, and not sure if you need to do this since it ran before, but I had to add --gekko-lowboost at the end.

From what I recall about the lights is that solid means power but not hashing and blinking mean power and hashing.
