I have tried to access my Flirc on 3 computers, but none recognize the device. The computers are a Windows 7 machine, MacBook and Windows 10. I tried manually installing the drivers and using the Zadig utility, but since it only shows an "unknown USB device (device descriptor request failed)" I am unsuccessful. Also, my understanding is that the Flirc is shipped with the XBMC setup. I plugged it into my Openelec Kodi machine, and after programming my Harmony 650 Remote for the Flirc, It did not respond to any inputs from the remote. It looks to me that I have a defective device. What can I do next?
