Dear Maintainer, I've noticed periodic screen flickering when using adb software. My usb-c screen is connected directly to the main board (Intel NUC). An other screen (not affected) is connected using DisplayPort. After a quick strace it shows up that this syscall turns my usb-c screen black for around one second: openat(AT_FDCWD, "/dev/bus/usb/004/001", O_RDONLY|O_CLOEXEC); A small C program can reproduce the issue. This kernel message is logged: usb usb4: root hub lost power or was reset More users have noticed similar problems before: https://www.reddit.com/r/androiddev/comments/hvwn1p/adb_causing_external_monitor_to_flicker/ Please note that root is not needed to reproduce the problem. Best regards,
