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

Found out what is causing the problem

I had a USB Hub connected to the computer in which I had connected a Tornado Spinner and a mouse hack spinner as well.   When I then plugged in my trackball to the computer directly it worked for a bit but then stopped on the Y-axis.   If I disconnected the USB Hub (ie: removing the Tornado spinner, mouse hack and USB Hub) then the trackball worked fine all the time.   This explains why on other computers the trackball worked fine.

I then started playing around and figured that if I connect the USB Hub by itself without anything connected to the Hub, then the trackball did not work again so I guess my problem is that the current power supply I have installed in the PC cannot support the USB Hub and Happ trackball mouse hack together.

I am assuming I have a 250Watt (or 300Watt) power supply in my arcade PC and I guess I need to get a stronger one.   The power supply is currently powering two hard drives, one CD ROM drive and a USB Hub which has a Tornado spinner and a mouse spinner hack connected.   I guess this was too much stuff for the old PC to handle.

I am assuming a new power supply would fix this problem .... do you all agree?

PS:  For now, I can get away with plugging my trackball and Tornado Spinner directly into the PC and they are working.   I might just forget about connecting my mouse spinner hack to the PC at all and then I will not need to buy anything.

It's possible, but maybe you have a bad hub and not a bad power supply?
surface tension:
I would agree that it sounds like the hub rather than the PSU.

The difference in current drawn with and without the mouse hack/trackball would be low compared to components in your PC under light/heavy load.

OK, I will try to get a new USB Hub and see what happens.

Ugh  :censored:  :censored:

I plugged my Trackball plugged directly into my arcade computer without anything else connected via USB and everything was working fine.   I left the computer on all night just so I could test it in the morning to make sure it still worked fine.  To my surprise, the trackball Y-axis did not work again.  This time there was no USB Hub, no Tornado spinner and no mouse spinner hack plugged into the computer at all.  

I am back to thinking this might be either my trackball mouse hack or the power supply.  

I have now connected my trackball mouse hack to my main home computer once again (where it always worked) and I am going to leave it connected over night and all day long to see whether it stops working as well.

(sigh)
