How do I know which version of the HUE HD Camera I have?

Please check the silver focusing ring around the lens. There will be some text printed on the ring. If you see the number 1.3 printed there, you have an older camera which requires drivers.

If you see the number 2.0, you have a plug and play model. The very newest plug and play models do not have a number printed around the ring at all.
