USB's on Mac Pro not working

[ShakeWellProd]

Hello, I tried plugging in a USB 4Gig Stick into the front of the Mac Pro and the back but the computer doesn't seem to recognize it. It works fine if I use the usb stick on my MacBook thou.

I used TechTool Deluxe Software to scan for issues and it says, "Passed."

Any thoughts? Thanks.

Update:

I realized that my Final Cut Keyboard has a USB port on the back. I plugged in the 4 gig stick and "Bam!" it works. I guess my USB on the tower are all faulty.


Are Mac's really all that?

But isn't your keyboard plugged into a USB port on the tower?

Yes, it is. It is the only USB device that will work so far.

Do you know why the memory stick works when it's only plugged into the keyboard?
