I just tested with "hcitool lescan" and it connected okay. So I
looked at a "hcidump" for the hcitool scan and for the Bluez scan and
they are a bit different.
Here is the one from "hcitool lescan":

It looks like Bluez is using random address and hcitool lescan is
using public address. I don't know why to use random or public.
hcitool lescan:
own address: 0x00 (Public) policy: All
bluetoothd:
own address: 0x01 (Random) policy: All
And the advertise address from the mouse is the same.
hcitool:
bdaddr C5:8C:97:E9:9C:81 (Random)
bluetoothctl:
[NEW] Device C5:8C:97:E9:9C:81 Arc Touch Mouse SE
Thanks.
