Yes, the bluetooth dongle is connected to a USB port on my laptop, and I have
noticed the "hub usbhid usb-storage" is list in the
AUTOSUSPEND_RUNTIME_DEVTYPE_BLACKLIST. But the bluetooth power saving is not be
disabled unless I add the device id of bluetooth in the
AUTOSUSPEND_RUNTIME_DEVID_BLACKLIST.

Yes, my runtime-pm.conf is like this, and the device id 8087:0a2b is the
bluetooth device id in my laptop.
