Hey Vidar, Could you try changing the line that reads
if(ret >= 0 || ret != -EPIPE) to if(ret >= 0 || (ret != -EPIPE && ret != -ETIMEDOUT)) to see if the camera recovers from error -110 (ETIMEDOUT) in the same way as it does from -32 (EPIPE)? I don't know much about store return policies but from my past experience some shops are pretty nice about that. Especially if you pretend to be an unexperienced user and tell them that "the camera just doesn't work". ;-) Anyway, we're obviously trying our best to come up with something that will save you from returning your camera.
