On Memento, if I use the standard demo program, https://learn.adafruit.com/adafruit-memento-camera-board/basic-camera, it works fine with the camera not connected to USB data. But when attached to USB, I can get I/O Error exceptions when it's trying to write a picture to the SD card. I can aggravate this by opening a file browser window in Ubuntu and double-clicking on the SD card drive.
It doesn't always happen, but once it starts happening, it seems to persist. It's not clear whether the card gets corrupted or not.
I am seeing this on 10.3.0-alpha.3, and it could be earlier. A bisect would probably help.
It would be worth trying file writes to an SD card without the camera logic to see if it also happens then.
