I have had a FLIRC USB (v2) for years. Today it stopped responding for no apparent reason. I swapped in a FLIRC USB (v1) that I also have, and that is working fine. So it's not the computer's USB side of things. The machine it's plugged into is a MythTV frontend that does not install any updates, so there hasn't been a firmware update. And it stays powered on 24/7 - it hasn't been rebooted.
I took the unresponsive FLIRC to my laptop to see if the FLIRC configuration utility could do anything, but it just says "disconnected".
Running FLIRC_UTIL says "device disconnected, can't run command".
Looking in Windows Device Manager, it doesn't show up at all as a device when plugged in.
So I guess it's just spontaneously died. But before I buy a new one, is there anything else I can try?
