AUTOSUSPEND_RUNTIME_DEVTYPE_BLACKLIST="hub usbhid usb-storage" So when you say a bluetooth mouse, should I assume that the mouse connect to a bluetooth dongle, which is connected to a USB port ? Because, as long as it gets enumerated as a USB device, which I suspect is what should happen here, it would be covered. > I think that the bluetooth should not suspend because of bluetooth > mouse.

The bluetooth power saving module is disabled by default. runtime-pm, which takes care of most devices supporting Runtime PM (most USB devices included), should by default blacklist most common USB type devices. Can you share your runtime-pm.conf ? -- Ritesh Raj Sarraf | http://people.debian.org/~rrs Debian - The Universal Operating System
