That is really interesting.

I test with enable my EHC1 XHC to S3 by setting enable in BIOS/Power Management
- USB Wake Support ( follow the patch describe : a0085f2510e8 Bluetooth: btusb:
driver to enable the usb-wakeup feature (v4.14-rc1)) 

then for testing use 
Bluetooth mouse (hid-generic 0005:046D:B008.0009: input,hidraw0: BLUETOOTH HID
v3.18 Mouse [Bluetooth Laser Travel Mouse] on 10:02:b5:98:71:4f)
and
Bluetooth touchpad (magicmouse 0005:05AC:030E.000B: input,hidraw0: BLUETOOTH
HID v1.60 Mouse [AL's touchpad] on 10:02:b5:98:71:4f)
and bluetooth headphones.
Only use bluetooth mouse can wake up my laptop (for sure).

I will try to find one bluetooth headphone to reproduce and also fix the wakeup
from BT (over HID) more properly at the same time.
