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:

Please note that root is not needed to reproduce the problem.


Best regards,

Hi

This bug was filed for a very old kernel or the bug is old itself
without resolution.

If you can reproduce it with

- the current version in unstable/testing
- the latest kernel from backports

please reopen the bug, see https://www.debian.org/Bugs/server-control
for details.

Regards,
Salvatore
