Well, I'm not getting those hours of my life back.

Right after sending this message, I recalled that I used powertop to do
"auto tuning". Sure enough, one of the lines was this:
Good Autosuspend for USB device UHCI Host Controller [usb6]
By disabling it, it runs this command:
echo on > /sys/bus/usb/devices/usb6/power/control
And it resolves my suspend issues on 4.20.3-gnu.
What sucks even more is that I had disabled those settings on the USB
controllers over a year ago (because it was putting my USB keyboard to
sleep, dropping the first keypress); don't know how it got re-enabled,
but the user is probably to blame.
Sorry for the noise, everyone. I hope that my suffering provides some
value to others.
This bug can be closed.
