Public bug reported:

I use two monitors with USB hub feature. My keyboard and mouse are
plugged into one of those monitors.

After Ubuntu boots, the keyboard and the mouse are dead. I have to
unplug the monitor's USB cable from the computer and plug it back in,
then the keyboard and the mouse are detected and powered on.

This happens in Ubuntu consistently, with all recent kernel updates.
Never happens in Fedora 35 or Windows 11 on same hardware (i.e. the
keyboard and the mouse are immediately usable after boot).

Ubuntu version: 21.10
Kernel version: 5.13.0-27-generic

Happened with earlier kernel versions too.

The output of dmesg and lsusb is attached.
