Here's the basic problem:  I have a custom-built machine running F8, kernel 2.6.24.5-85 and it doesn't detect anything USB.  I included my complete system profile below.

When I first built this computer about 5 months ago, USB keyboard/mouse didn't work.  I attributed that to needing drivers loaded for first use.  I should note though that my external USB drive did work.  One day, I'm not sure how, the USB keyboard mouse worked, and it worked for like 2 weeks.  Then, as quickly as it came, it went.  Again, not sure how.  This time though, nothing worked; no keyboard, no external HD, no nothing.  That's where I'm at today.  Even when I plug in a flash drive that has a read light on it, the light doesn't come on at all (the drive works fine on other comps) like it's not even getting power.

I've tried researching this online, but all I can find on this sort of problem is for older kernels that don't have the USB-required modules loaded.  I'm not super familiar with hardware stuff in Fedora, but here's a snippet from lsmod that includes the usb modules (I think).

[root@localhost robb]# lsmod
Module                  Size  Used by
uhci_hcd               30561  0
ohci_hcd               28997  0
ehci_hcd               39501  0

I checked BIOS to make sure USB is enabled, and it is.  I can't figure out if the problem is with the computer (specifically the mobo) or the OS.  Other than that, I'm out of ideas.  I can run any sort of diagnostics that would shed more light on this.  Thanks in advance for any sort of help you can give.
