I'm having what appears to be the same error as reported by Jebb Stewart ("Problem pairing wiimote device via bluetooth", 2012-10-10), but with a Logitech DiNovo Mini keyboard/mouse device, and the dongle that comes with it. In my case, the problem is possibly more severe than Jebb's, as the Logitech device goes into a power saving mode after only a few seconds of not typing, producing a bluetooth disconnect, and then reconnects as soon as you touch it again. Therefore, in normal usage, it is disconnects and reconnects a lot. The sysfs error I see is, AFAICT, identical to Jebb's. I'm running a vanilla 3.6.8 kernel. An example of the error as it occurs for me is attached.
