I ordered my Pi when they first came out, when I first used it I noticed that after a couple of minutes of running the keyboard/mouse stops working and the networking stops working (I understand that these share a bus?). I put the Pi in a drawer and just sort of forgot about it since I didn't actually need to use it at the time (I bought it to fit into my car).
Fast forward to now and today I created an SD card for it with the latest Raspian build and poped it in. It booted up fine and my wireless logitec keyboard and mouse worked fine. I started X and after about 2 minutes of use they stopped working. Bugger. I switched it off, waited a few seconds and switched it back on again. This time it wont let me use the keyboard at all, not even to log in.
So far I've tried three different adapters (two known to work on other Pi's), three different SD cards (two known to have a working OS) and two different keyboard/mouse combo's (again known to work on other Pi's).
Does anybody have any suggestions as to what to do next or do I need to try and get this replaced under warranty? A friend mentioned to me that he recalled a thread where someone had similar issues (which I now can't find) which were resolved with a firmware upgrade however I don't seem to be able to find a way to upgrade the firmware from outside a distro (unless I'm just searching for the wrong things!).
Any help you can provide is much appreciated.
