I have a Dash 1.2 Rev D, a Rev E, and an earlier model with a red jumper. The Rev E has been working fine on my mac for a few weeks. Suddenly, it will no longer appear in the port list when I plug it in the USB port.
ls -al /dev/cu*
Does not show the device. Previously, it did.
I tried my Rev D. No luck.
I tried the old one with the red jumper - it works fine. I can’t use this old one for what I need to do. I need the Rev E working, but the point is: something happened in there.
I think there was a firmware update I agreed to and I’m blaming that in my head at the moment. Could this be the case?
I pulled out a linux box and installed everything on it - same story it seems. I can pick up the red jumper (old one) but neither of the newer ones.
I used a powered USB hub to make sure it was not power. I can load a regular UNO on either machine with no problem. The old red jumper model works fine on both.
I’m stuck. I’ve done everything I know to do and I don’t have a clue what’s going on.
