Just got one of these dongles in the mail the other day, and it causes my PI to lockup and corrupt its memory card more often than not. I am running the PI off of the Adafruit 5.25V USB power supply and only have the HDMI and a standard USB keyboard hooked up. I'm am running Occidentalis. Any idea where I start with troubleshooting this? I have tried it on a second SD card with similar results so I think we can rule that out.
