Right underneath the soundcard. 16s into the video you posted.
exactly as in the first photo shown in this comment Re: Need help with floppy drive not working and/or alternatives. Also USB Support?

I think I found it....

So I need a multimeter like this:

And USB like this?

Will Windows 98's default driver handle this? I also don't know how to use a multimeter. Which I could try to find info on...but yeah

Those items should be all that is needed. The USB ports might be disabled by default in the CMOS settings, so be sure to verify that they are enabled. If you installed Win98 the preferred way (by copying the CAB files to the hard drive) then you won't even need to fish out your Win98 CD. If the ports are enabled in the CMOS settings, you ought to be able to have a look in Device Manager and see them now.

Actually, it was enabled in CMOS, I enabled it before installing my PCI card. Could that have been what my computer was detecting, and not my PCI card? Could that be why my PCI USB card isn't working? I need help getting Win98se USB working

You would need to verify that the pin header on the motherboard matches this illustration by setting the meter to check DC voltage. Pin one should be +5 on both sides, and pin four should be ground on both sides.

There are many reason why the USB card might not be working - one thing that comes to mind is that it might rely on 3.3 volt voltage that isn't supplied by your motherboard's early PCI slots. If the USB ports on the motherboard will work, you'll be much better off using them.

Ok so with the computer running test one end to the 5v and the other end to the ground. If I do it wrong way it won’t hurt anything but will just display as incorrect. Am I understanding that right? Thank you for the help..

That is correct. Be careful with the meter's probes because you do not want to accidentally cause a short circuit by touching more than one of the USB port's posts at a time. The motherboard's USB header almost certainly will match the eight pin one that I've posted, but early USB implementation was all over the place so there is no substitute for being certain.
