The DELAY_INIT quirk only reduces the frequency of enumeration failures with the Logitech HD Pro C920 and C930e webcams, but does not quite eliminate them. We have found that adding a delay of 100ms between the first and second Get Configuration request makes the device enumerate perfectly reliable even after several weeks of extensive testing. The reasons for that are anyone's guess, but since the DELAY_INIT quirk already delays enumeration by a whole second, wating for another 10th of that isn't really a big deal for the one other device that uses it, and it will resolve the problems with these webcams.
