Was there a resolution to this thread? I am experiencing this issue. All steps above to troubleshoot have been taken.
GUI = v3.9.8
Flirc = v2 (metal)
This is happening after I recently moved. The Flirc device has worked on this box previously. This time, when I plugged in the device, I was prompted to do a firmware upgrade, which I did. Since then, the device has been "Disconnected" in the GUI. The GUI installed goes through installing drivers, and Windows appears to finish installing the device when I plug it in.
I have uninstalled and reinstalled the device and the GUI. Rebooted, ran everything as administrator, etc. Any help is appreciated!
