New testing today, with latest kernel update.

Booting with Unifying dongle plugged in:

guillaume@massada:~$ uname -a
Linux massada 5.4.0-26-generic #30-Ubuntu SMP Mon Apr 20 16:58:30 UTC 2020 x86_64 x86_64 x86_64 GNU/Linux
guillaume@massada:~$ grep . /sys/bus/usb/devices/*/power/wakeup
/sys/bus/usb/devices/1-2/power/wakeup:enabled
/sys/bus/usb/devices/1-8/power/wakeup:disabled
/sys/bus/usb/devices/usb1/power/wakeup:disabled
/sys/bus/usb/devices/usb2/power/wakeup:disabled

Unplugging the dongle, and then plugging it again, same USB port:

guillaume@massada:~$ grep . /sys/bus/usb/devices/*/power/wakeup
/sys/bus/usb/devices/1-2/power/wakeup:disabled
/sys/bus/usb/devices/1-8/power/wakeup:disabled
/sys/bus/usb/devices/usb1/power/wakeup:disabled
/sys/bus/usb/devices/usb2/power/wakeup:disabled

Waking the computer from sleep with mouse or keyboard does not work anymore.

guillaume@massada:~$ sudo -s
root@massada:/home/guillaume# echo "enabled" > /sys/bus/usb/devices/1-2/power/wakeup
root@massada:/home/guillaume# exit
guillaume@massada:~$ grep . /sys/bus/usb/devices/*/power/wakeup
/sys/bus/usb/devices/1-2/power/wakeup:enabled
/sys/bus/usb/devices/1-8/power/wakeup:disabled
/sys/bus/usb/devices/usb1/power/wakeup:disabled
/sys/bus/usb/devices/usb2/power/wakeup:disabled

Waking the computer from sleep with mouse or keyboard works again!

>> This should be re-enabled by default whenever you (re)plug such a dongle.
