3.5.1 hid_generic causes mouse locking until a button is clicked

	I upgraded from 3.4.4 to 3.5.1 kernel and now I see the new
hid_generic module is causing problem with my mouse (a regular Logitech
USB optical mouse).

	The problem is: after 2 seconds without moving the mouse, the
pointer will NOT move again UNLESS I click a mouse button.

	So now I have to click a button everytime I want to "unlock"
the mouse pointer. It didn't happen with 3.4.4 so it's clearly a
regression.

Any hints? I can try patches. Thanks.
