Raspberry Pi Logitech C920 Timelapse

I spent some time messing around getting Time Lapse and HTTP Live streaming
working on my Raspberry Pi

I'm using a raspberry pi, Logitech C920 webcam and some powered 4 port hub from amazon

Had a lot of problems with firmware (Make sure you update to the, as of April
18th 2014, beta firmware and set the USB concurrency flags to 0x7 (or something
like that).)

I also had problems with shitty USB cables, but now its pretty stable.

What firmware are you talking about? The camera? the Raspberry Pi? Also, how do you set the USB concurrency flags?
