Just to clarify, I have tried the solutions laid out here (I don't have a mac to try this on and a linux live disk didn't work either) :
I've tried this too: https://support.flirc.tv/hc/en-us/articles/200984473-Manual-Driver-Installation
The device shows as installed with device manager, but doesn't show as connected on the Flirc software.
Has anyone else had this issue? Have you been able to get it to work?
