Hi, everyone. Been using a brand new thinkpad t14 gen 2 (AMD) for a while, the biggest pain now is that I can not find my bluetooth keyboard (logitech MX keys mini), and bluetooth mice (logitech m720) using bluetooth. I've been search online for whole day now and can not find any clue on this yet.
I've checked that the bluetooth can find my JBL speaker and my phone and my filco keyboard and other macbook, it just can not find the logitech devices. (I can use the logitech unified receiver no problem tho)
Also I can find these logitech devices if I change to my dual-boot windows system. So should not be hardware issue.
Things I tried:
1. I'm not sure whether it's some LE(low energy) issue, so I installed bluez-utils-compat and use `hcitool lescan`, no result.
2. read a post online and install bluez-hid2hci, no effect on this. it does fix the gnome-bluetooth-3.0 issue that toggle off the bluetooth switch will totally remove the bluetooth and can not bring back.
3. tried everything listed on arch wiki, no effect.
My bluetooth modal
lsusb shows the bluetooth modal as `Bus 003 Device 003: ID 0489:e0cd Foxconn / Hon Hai Wireless_Device`

I just booted my laptop this morning and, without doing anything, the keyboard and the mouse all can be found by my bluetooth now. I don't know the reason behind, so I'll just post my packages here for reference:

local/bluez-hid2hci 5.64-2
Put HID proxying bluetooth HCI's into HCI mode
local/bluez-libs 5.64-2
