Just finished building my trackball panel and hooked it up tonight.
When I plugged in my USB Opti-PAC, it loaded some stuff, but wasn't working in either MAME32 or Windows XP. I shut down the machine and looked at all my wiring and the jumper settings just to make sure I had everything set up right.
When I rebooted and plugged the Opti-PAC back into the USB port, I got the following error message: "One of the USB devices attached to this computer has malfunctioned and Windows does not recognize it. For assistance solving this problem, click this message."
If I click on that message, it takes me to my USB devices and lists the Opti-PAC as an UNKNOWN DEVICE.
I did some of the troubleshooting steps listed on the Ultimarc page, and it would appear I have what is referred to as a "Voltage High" problem. I pulled all the trackball wiring off the Opti-PAC and plugged it in just to see what it'd do, and it still generates the error message.
Can anyone give me some pointers to get me going in the right direction?
