Dumb Grounding Question
PacManess:
Ok, here is my stupid question for the day.
My IPac4 isn't working, major weird problems between intermittent keyboard error on bootup to just plain nothing doing at all.
I have grounded the thing like this: one end into ground port 1, daisy chained to all devices, then the other end into ground port 2...which basically makes a grounding loop. Would that cause problems? Could it be so simple as to unplug one of those groundy ends and BAM! I have arcade controls?
Any ideas?

A ground loop is not recomended. Disconnect one of the grounds and see what it does.
PacManess:
Sweet! I'll give it a shot when I get home from work. See, today, I worked (am working) 14 hours. Good lord have mercy. And I have to do it again tomorrow. So good times. At least obsessing over getting my IPAC working is giving me something to occupy my nugget.
So anyway, rambling aside, I'll give it a shot when I get home. Hopefully much love and killing will happen joystick and buttons style.

Why? I thought that would just add some redundency?

Grounds are complex beasts that do not obey any of the normaly obvious rules. Electrical engineers can take classes to study just grounds at the graduate level. That is more education than I have, and I've seen the math, it is harder than I want to deal with.
I just follow simple rules: no ground loops. If this way audio you would hear strange sounds, and never be happy. This is digital, which is a little more immune, but in this case.
Mind you might have some other problem, but start by eliminating a known potential source of problems.
