Grounding a USB trackball necessary?
Ninten-doh:
This is probably a really dumb question, but I want to be sure. I recently purchased a 2 1/4" Happ USB trackball and it has the green grounding wire that stick out of it. I thought that the USB connection would ground the unit, no? Is grounding the green wire still necessary?
Timoe:
This is teh GOOD QUESTION
NO you do not need to ground that sucker. Infact, just take the green wires off all together.
2600:
Necessary.. depends who you ask?
I think my opinion is in the minority, but yes ground the trackball. Ground your trackball, your spinner, and anything else that may need it.
Timoe:
Why?
and
how?
DaveMMR:
I was about two days away from asking the same question Ninten-doh.
Basically, according to the Optipac instruction page, it just attaches to any ole piece of metal to prevent static build-up (the same reasons you would wear a wrist strap, or at the very least, touch a piece of metal, before working on the insides of a computer).
I was going to ask because I have no convenient way of attaching it to something (panels swap out). I was just going to screw it down, hide under a blanket, cover my eyes and hope that somehow, everything turns out okay.
