Fix for Acer Bluetooth Optical Rechargeable Mouse

This patch fix a problem with Acer Bluetooth Optical Rechargeable Mouse where the cursor gets stuck at screen's upper-left corner. Even the touchpad of my notebook (Acer Ferrari 4005) cannot move the cursor when the bluetooth mouse is turned on. Using an input session instead of hid session solves this problem although the cursor moves a little sluggishly with the bluetooth mouse. It moves correctly using the touchpad. I do not know if there is a better implementation or a quirk for this problem, if it exists let me know.
