USB disconnect allways after some time

[MacBreaker]

Hi there,

 

System:
root@OPiPC2-Main:~# uname -a
Linux OPiPC2-Main 4.14.18-sunxi64 #26 SMP Fri Feb 9 17:14:48 CET 2018 aarch64 GNU/Linux

 

System diagnosis information will now be uploaded to http://ix.io/18C3

 

I use different Orange Pi's for monitoring with mjpg_streamer and Kerberosio.
It works like a charm with Legacy Kernel (Orange Pi Zero+2, Nanopi Air and other H3 devices), but with Mainline Kernel I always have problems.

The USB port to which I connect my webcam, is disconnected again and again after some time.

I have also changed the type of webcam without success.

 

In messages I only found:

After a reboot, the device is missing again. Only after a power cycle it shows up.

Where is the problem, any ideas?

Problem solved by using Kernal higher than 4.14.40.
