OK, here's my current situation. What can I do remedy the problem?
HAPPS 3" trackball using PS/2 mouse hack.
Slickstik Spinner plugged up USB
LCD Topgun plugged up USB.
Windows sees all 3.
Windows uses all 3 as a mouse.
MAME uses trackball, and spinner, but not the lightgun
If I unplug the spinner, MAME uses the trackball and lightgun
Using -verbose in mame with trackball, spinner, and lightgun shows 2 mice NOT 3.
Using -verbose in mame with trackball and lightgun shows 1 mouse, but the lightgun WILL work.
How can I get around having to unplug the spinner to use lightgun?
Why does mame not see all 3 "mice"?
