Realtek RTL2838 DVB-T tuner failure

It would appear that my Realtek RTL2838 DVB-T tuner has failed. I can no longer get it to record any more using TvHeadEnd. I noticed I hadn’t got any recordings the past few days and I’ve just checked all the connections. At this stage I think it’s safe to conclude that it’s gone.

It certainly didn’t last very long. I might end up getting another one, however not in a big rush. I need to do some other work with the hardware, so I might move onto that project in the meantime.

I note that dmesg output is showing the following, which based on some of the word is related to the hardware failure of the device.
