You have connected the molex power from the PSU to the 4 pin molex plug on the card? If not, that needs to be done. Is the USB controller on the card the same as the controller on the motherboard? If they are, one will knock the other out. If not, the card may just be incompatible, but have you tried it in a different slot? I am surprised you went for a USB 2.0 card, I would have got a USB 3.0 card......

Mr T is quite right. Very likely, a conflict of IRQ/DMA assignments. But that card needs a PSU connection.
Has been a problem for decades, when duplicating an on-board feature with an add-on card.. device conflict due to using the same IRQ and DMA. If the duplicate device card has jumpers, then the IRQ/DMA may be changed to avoid conflict. Some may be a "soft-set" type, using a small program that comes with the device card.
If you don't have enough USB ports, get a multiple-port USB hub that is self-powered, not drawing power from the system. For external devices that require high speed, connect directly to a USB system port. For other devices, they will mingle happily on a hub.

I didn't have it plugged in to the PSU and I bought it a long time ago ... just using what is on hand. I will try it with it hooked up to the PSU and see what happens. Thanks. :)

Well sir ... I decided since the PCIe card works on my AMD computer I will use it on that one and buy a 4 port usb hub 3.0 with its own power source ... that will solve my problem ... I just needed one extra port for my web cam so now I will have two extra ports. Thanks for reading my posts. :D

Better to have the powered USB hub. It is backward-compatible to older standards, so any device connected should work well.
Guess the problem is resolved.
A USB port only provides 1/2 amp or 500 ma of current, which is the max on most devices. A USB hub can provide up to 1 amp per port, on some models.
But forget the "USB coffee warmer" or "USB fans or lights". Power any of those gadgets directly from a USB charger!
