Multi cams, Philips pc 900 crash after few minutes

[L3o-pold]

I have a Raspberry PI 2 model B with a Raspberry Pi camera module (black) and a Philips pc 900 (USB).
Philips pc 900 crash after 30 minutes and seems busy when motioneyeos tries to restart it.

Here is my log files

The interesting parts seems to be:

The crash log I presume.

[2] [NTC] [VID] vid_close: Closing video device /dev/v4l/by-id/usb-0471_0329_01690000CE000000-video-index0

And the unsuccessful automatique restart.

It seems like a buggy driver or something fishy at a lower level. I wouldn't know what to do about this. Does it work on Raspbian with motion?

Yes it works but I will try with a longer test session. The camera works out of the box by the way.

Looks like activating Automatic Brightness for the Phillips cam fix the issue.
It think that the cam timeout after some inactivity and the automatic brightness option keeps it alive.
I noticed that when the cam crash, you can restart the stream by pressing the top button (the button is supposed to take a picture), and you don't need to restart the Rasp.
