where the cursor gets stuck at screen's upper-left corner.

Even my notebook's touchpad is not able to move cursor when the bluetooth
mouse is connected to my Acer Ferrari 4005 notebook.

Using input session instead of hid session solves this problem although
the cursor still moves a little sluggishly with the bluetooth mouse,
cursor moves correctly using the touchpad.

My bluetooth mouse used to work well (no sluggish) until kernel 2.6.21,
since then the problems are getting worse with each kernel release (it got
sluggish in 2.6.22 and this this upper-left corner problem appeared in
2.6.28 or 2.6.27).

The patch adds a general quirk handling framework to the HIDP core and
then uses this framework to implement a quirk for this device.
