MacOS joystick problem

I have been informed of a bug in the SDL joystick code where it freezes up
the mouse on the affected system upon initialization. It seems that a
certain Mac with MacOS 8.6 and a USB-PCI-Card adapter with a USB printer
experiences this problem. The printer is the only USB device present. The
mouse is ADB. As far as I can tell, the software configuration of the
affected system is legitimate, as other ISp-aware apps seem to work as
expected. I would delve deeper into this problem, but I’m no expert on ISp,
and I figure it would be easier to get the original author’s feedback first.

So, show thyself and claim thy bugs!
