Yep that sorted it :D great work, I'd have been a bit stumed otherwise as I just hammered every key on my keyboard and still couldn't find where home had moved to (I'm assuming it's now a media key or other non-standard key that's missing from my keyboard).

Mines gone the same way after the update. It looks like Amazon have changed the home key mapping so they can apps like Firestarter from detecting home key presses. I'm going to plug a usb keyboard in and try to find where it's moved to.

Hi Jason, just to let you know I haven't forgotten about this. My son decided he wanted to be born 6 hours after my last message, and on top of dealing with a newborn I've also been running an Indiegogo campaign so things have been a bit hectic. I'll get the readings as soon as get 10mins to myself ;)

Here you go, 2 meters both the same reading http://1drv.ms/105bhDY I'll have to get back to you on part 2 as that involves dismantling stuff and I need to get to bed.

Of course, everyone should have a meter ;) Before grounding I was seeing 1~1.5v floating around on the shield.

Looks like that's the exact same setup as mine.

Well the easy way to test if you have the same issue as me is to hold your finger on the metal shielding of the USB, then try the remote and see if the keys have stopped sticking. You can also try touching the shielding while the keys are stuck repeating and see if they stop.

Hi Mathead, my issues were definitely caused by some interference/voltage on the USB shielding - I was able to measure it on a multimeter. Since adding a permanent earth to the shield my flirc has worked like a dream :) I had tried the flirc with no casing/taped up casing before with no success.

I soldered the earth wire to the outside of a cut down USB plug, and inserted it into the top USB port on the Pi. (excuse the dust)

Ok, well I'm totally convinced now my issues were caused by interference on the ground. Since adding an earth point the flirc has been working like a dream (and if I remove the earth it plays up again) :)

I assume you're talking about this thread http://www.hifi-remote.com/forums/viewtopic.php?t=15142&postdays=0&postorder=asc&&start=0 I've been watching it for a while :)

dmesg results. After fresh boot - http://pastebin.com/JtUZcJYp Extra lines after testing - http://pastebin.com/6HFQybEh I think the extra lines are unrelated as I repeated the test a few more times but nothing else was added. Let me know if you need me to try anything else.

I'm in the UK so the electrical sockets are grounded although I'd say none of the hardware is actually grounded in standard configuration (it's grounded now as I've wired the USB shield to ground) - TV and Sky box are on unearthed 'figure 8' leads which are only live/neutral, and the Pi runs on an iPad 5v supply. On a side note the TV on my upstairs setup (which works fine) uses a 3 pin 'kettle lead' which is grounded. Yep can do, give me an hour until my daughters gone to bed (she's using the TV at the moment).

I've tried it with other cables, and also plugged directly into the Pi itself with no joy. It works fine if I plug the flirc into my laptop or my Pi setup upstairs. The issue is potentially my Sky TV box as things improve if I unplug the HDMI lead for that. The shielding for the satellite dish grounds to the Sky box, which is a shared ground for the HDMI so maybe it's causing some interference?

Ok, well the flirc working after swapping the USB seems to have been a fluke and it stopped working again :( however it brought me back to putting my finger on the USB plug to get it working - here's a vid demo of that http://1drv.ms/1zc7T63 It's hard to see but at the beginning I have my finger on the USB and it's working fine (other than the sticky button on my remote). When I take my finger off it works briefly then the key gets stuck - as soon as I out my finger back on the USB the sticky key stops. Looks like some kind of earthing issue so for now I've run a wire from the Earth on my house mains and attached it to the USB which seems to do the trick.
