    Hello,
    I am observing the following really strange behaviour - initially everything with connecting an external usb camera was ok. My usb camera app received events asking for permissions for using usb camera. But after 3 or 4 full charges the app stopped receiving permissions. I checked with couple other apps but again no permission. If my battery drops under 60% suddenly everything is ok again and the app detects the camera. It is stranger, that before full detect of the camera the app starts some kind of permission loop. I click allow and after 2 seconds the permission dialog shows again and so on... I checked the source code and appears my USBManager returns empty device list. For me it looks like some kind of battery optimizer or usb state optimizer doing it. I will be more than happy if someone can help me with this issue.

    Here is some log from dmsg.
