Can't init facetimehd

[otisliao1]

Hi there,

Thanks for the hard work of creating this driver. I installed it on my Macbook Pro 15" (Middle 2015) and I encounter this issue of PCIe link failure, could somebody do me a favor?

I reboot my laptop and the init process goes further and then stop at error -22

Cheese says "No Device found" I am on OpenSUSE 42.3 Leap

Looks like your camera doesn't report a proper sensor id. We've change so that this is no longer fatal. The latest version in master branch will fix your problem.
