The problem is clearly visible on a Dell Precision 5750. On a ThinkPad

issue?

Such settings are in the /sys filesystem as text files you can read and
write to. Writing to them is not remembered across boots though --
that's what software like powertop or tlp does.
So you can script writing to /sys/SOMETHING to control power management.

"Good" in PowerTop usually means it is set to sleep. It sounds like the
setting you want is actually the one labelled "Bad".

After enabling the HWE stack on my Kubuntu 18.04.3 64bit and upgrade to Kernel

An upgrade to Kubuntu 19.04, Kernel 5.0.0-23-generic, didn't solve the issue.

To manage
First ensure you don't have 'tlp' installed.
Second, I can only answer by Googling. Maybe changing your kernel
command line to disable autosuspend of USB devices:

management.html

Day 5: Issue comes back again (after suspend). Those two unknown devices
switched back to "Good". This time I toggled one of them to "Bad" and
the issue is resolved.
How do I make the powertop changes permanent?

I see. There are two "Good" unknown autosuspend USB devices, not sure
which one is my mouse. I can't find it in "Bad" either.
Anyhow, the issue seems resolved currently.

I think you're looking at the wrong line there. The line you want is:
Autosuspend for USB device ...
It sounds like the line for your mouse says "Good", which is actually
bad news. Because it means the kernel is powering down the USB device
for power savings. So a delay is expected.
