After several weeks of no issues, after downloading a program from VS to the Cerb40, Windows8 came back with Device Not Recognized.
I plugged in my spare Cerberus main board, and it was recognized. So I downloaded to it, and now it is not recognized either.
What to do? Two dead modules.
This is using USB, direct to PC, no hubs, tried multiple ports. Tried reinstalling GHI USB drivers using the setup program. No external power or connections. Just the modules.
Nothing special about the program. Run an RLPLite command, print a debug string, and then while(true);
