Public bug reported:

When I connect my Logitech Precision Gamepad (or the machine starts up
with it connected) it exhibits activity on both axes until I press a
button/press the d-pad.

UPON PLUGGING USB CONNECTOR IN:
===============================
Driver version is 2.1.0.
Joystick (Logitech Logitech(R) Precision(TM) Gamepad) has 2 axes (X, Y)
and 10 buttons (Trigger, ThumbBtn, ThumbBtn2, TopBtn, TopBtn2, PinkieBtn, 
BaseBtn, BaseBtn2, BaseBtn3, BaseBtn4).
Testing ... (interrupt to exit)
Axes:  0:-32767  1:-32767 Buttons:  0:off  1:off  2:off  3:off  4:off  5:off  
6:off  7:off  8:off  9:off 

AFTER PRESSING ANY BUTTON OR THE D-PAD:
=======================================
Driver version is 2.1.0.
Joystick (Logitech Logitech(R) Precision(TM) Gamepad) has 2 axes (X, Y)
and 10 buttons (Trigger, ThumbBtn, ThumbBtn2, TopBtn, TopBtn2, PinkieBtn, 
BaseBtn, BaseBtn2, BaseBtn3, BaseBtn4).
Testing ... (interrupt to exit)
Axes:  0:     0  1:     0 Buttons:  0:off  1:off  2:off  3:off  4:off  5:off  
6:off  7:off  8:off  9:off

EXPECTED BEHAVIOUR:
===================
Both axes (0 & 1) should be "at rest" (i.e. 0, not +/- 32767) when the gamepad 
is initially plugged in.

Note - I'm not sure whether the d-pad should be classified as a pair of
axes or a pair of hats - it is a digital d-pad though, *not* analog.
