HELP: Trackball w/Optiwiz USB interface results in left/right not working
<< < (3/10) > >>
RandyT:

At this point, you will need to isolate where the issue is occurring. If you now know exactly which axis is causing you problems, you need to swap the axes and see what happens.  If you swap them and the problem changes to the left/right, then you still have a trackball issue.  If the problem remains on the up/down, then you have an interface or CPU problem.

I already swapped the boards on the trackball long ago and the issue remained on the up/down axis , however, I will try to remove my trackball tomorrow and test that again.

Any ideas I can try first assuming this is an interface or CPU problem?

Actually since my USB mouse works fine all the time then how can this be a "CPU problem"?

How can it work perfectly on a different computer, but not the one you are having issues with?  That, and the fact that you had a similar issue with your mouse hack, are two things which keep the CPU (PC, whatever) in the list of possibilities.  If it does the same thing on both systems, then it's the interface.

Based on what you just reminded me there is a actually no reason to switch boards to test it out again since the trackball works perfectly on my home PC all the time.

Basically, I agree with what you are saying.  This is why I thought it could be the power supply last time I was looking into this issue.    I eventually got annoyed and stopped looking into this problem before since I spent money on a new trackball and spent a bunch of time hacking a mouse to find out it did not work.  Thought my mouse hack was bad so I decided to buy the Opti-Wiz interface and still the problem existed   :P   I just did not want to spend another $80-$100 on a new power supply hoping that would fix the problem.  If it would not fix the issue then I would be out about $300 on trying to get a new trackball working   :o

Anyway, I decided to see if anyone had any other things to try before I purchase a power supply route.

[EDIT]
Hmmm ..... I wonder if connecting my trackball into a self-powered USB hub would solve my issue?  This way my Mame PC would not be powering the trackball directly.  The USB Hub would be powering it I guess.  I might try to borrow one to test this out.

unclet:
I tested with my self-powered USB Hub (ie: plugged into the wall) and this is what I found:

1) Only connecting my USB mouse to my Mame PC results in the mouse working all the time

2) Connecting only my USB Hub to my Mame PC and only connecting my USB mouse to the USB Hub results in the mouse working all the time

3) Only connecting my trackball (via the Optiwiz USB interface) to my Mame PC results in the trackball up/down direction working right away but then slowly stops working after about 20-30 seconds.  The left/right direction works fine all the time

4) Connecting only my USB Hub to my Mame PC and only connecting my trackball (via the Optiwiz USB interface) to the USB Hub results in the trackball "immediately" NOT working in the up/down direction.  The left/right direction works fine all the time
