I was limited by stupid "Exposure Failed" errors again. I don't know what the fuck is wrong with this camera. It works perfectly 99.9% of the time, but just randomly decides to be unresponsive for long enough for the ASIair to wait minutes doing nothing, timeout, throw an error, and break whatever it was doing at the time.
Searching online suggests it has something to do with the USB cable, but I've tried 4 different cables (including the one that it came with) and it's happened on all of them.
