>Description:
	

The C64 Emulator pkgsrc/emulators/vice does not recognize the firebuttons
of the (since january available) Competition Pro USB joystick. This happens
because hid_get_item(3) reports 255 as hid_item.logical_maximum and vice
expects at least 1/3 of the logical_maximum to be reached to emulate a
digital joystick but the joystick gives only 1 if the button is pressed.

I do not know, if the joystick reports broken numbers or if hid_get_item(3)/
hid_get_data(3) reports faulty values or vice is overoptimistic in its
assumptions about buttons. So I report this here, hoping somebody can
figure out what exactly is broken.

The same happens with NetBSD 2.0.

>How-To-Repeat:
	
Compile Vice out of the pkgsrc, plug in an Competition Pro USB joystick,
select USB Joystick in Vice and start any game which uses the joystick:
The axis work fine, but none of the four firebuttons works.
>Fix:
	
With this patch applied the Competition Pro USB works. But I do not now
if this breaks other joysticks/input devices, because I own only this
one joystick. So testing is recommended before committing it.
