Why is the camera on openwrt disabled?

Question

Network administration

I installed the camera according to this manual. h-wrt.com/ru/doc/webcam
Camera Logitech HD Pro Webcam C920
I connect a USB hub to a TPLINK 842ND OPENWRT 14.07 router and a camera to it.
Number 001/029 ID 1a40:0201 USB 2.0 Hub [MTT]
Number 001/037 ID 046d:082d HD Pro Webcam C920
Number 001/039 ID 152d:2329 USB to ATA/ATAPI bridge
The problem is this. The camera turns off by itself. Reconnecting the camera helps. If necessary, I will add a kernel and system log.
What to do with the camera and who is to blame?

Answer 1

The need has come :) Output dmesg, pliz, with the moment the camera is turned off. Maybe add logread at the same time.
