FIXED! (New Happ arcade trackball quickly stops working in Y-axis direction)

Keep in mind, $15+shipping would let you get away from the "hack", although it's still uncertain if that is the root of your troubles.

It sounds like you've already taken the hub out of the equation, but I had a PILE of trouble with my spinner and 2 trackballs until I replaced my UNPOWERED hub with a good POWERED hub.

That is what solved the probs for me.

There just wasn't enough juice on an unpowered hub for all the devices.

I'm powering a UHID, 2x U360s from a hub. 
The UHID drives 2 spinners and a Happ trackball and 1 LED (plus a whole lot of switches). 
I've not seen any problems with this setup.  The hub does support externally powering but worked fine without it.
I will be adding 4 more LEDs per CP, but my guess is that these devices don't draw much current, although it's easy enough to measure.

Well the only reason I am not buying an Optiwiz yet is that I cannot explain why the trackball mouse hack works on my other main computer all night long.  I woke up this morning the and trackball works fine.  

Also, my USB Hub I was using was a "powered" hub.  Although since the hub is not connected to the PC anymore this cannot be the source of my problem.

I guess I will eventually just buy an Optiwiz.  If that does not work then I will buy (or find) a new power supply with more wattage than I currently have.

I have no other ideas.

PS:  If I buy an Opti-wiz no-solder version for $15.00+$7.60 ($22.60) then will the Opti-Wiz come with holes to allow AWG 18-21 sized wire to fit and be soldered?   Is there anything else to making the Opti-wiz work?

According to the website, if you order the "solder" version, it doesn't have headers.
You should be able to solder 20awg wire directly to it.
