Got a Pi a few weeks ago and got it up and running with a Debian distro. USB worked with a wireless keyboard/touchpad (approved of in the RPi wiki), ssh worked. Also tried RaspBMC and OpenElec XBMC - in both cases they seemed to ignore USB once XBMC itself was running, although (IIRC) they recognised the keyboard while booting up.
Put it on one side for a while, then returned to it, and using exactly the same hardware (including PSU), started getting strange errors - on boot, it keeps reporting new USB device detected, regardless of whether anything is actually plugged in, then kernel panics. This happens with Debian, OpenElec and RaspBMC. As there is a significant difference in behaviour with no change in external hardware or software, it appears to me that something untoward has happened to the USB port IC.
Has anybody else had this? Is it likely to be a hardware fault? And if so, how do I return it to Farnell/Element 14 for exchange?
