Does the 8500 even have PCI slots?  It's been so long since I looked in 
one :)  Anyway.. the easiest thing to do would be to see if YDL 
automatically found your usb card at boot.  the easiest way to do that is 
to simple do "dmesg | grep usb"  if ydl found your card it should be 
reported there and you can just start using your USB devices happily.

On my Dell the output would look like this (the output will be similar on 
YDL):
[nathan@mooby nathan]$ dmesg | grep usb
usb.c: registered new driver usbdevfs
usb.c: registered new driver hub
usb-uhci.c: $Revision: 1.275 $ time 11:43:19 Dec  1 2003
usb-uhci.c: High bandwidth mode enabled
usb-uhci.c: USB UHCI at I/O 0xff80, IRQ 14
usb-uhci.c: Detected 2 ports
usb.c: new USB bus registered, assigned bus number 1
usb-uhci.c: v1.275:USB Universal Host Controller Interface driver
usb.c: registered new driver hiddev
usb.c: registered new driver hid
[nathan@mooby nathan]$ 

If not, you may need to manually load the driver with modprobe.  The 
specific command for this varies because there are two different types of 
USB bridges, which require different modules, usb-ohci or usb-uhci.  If 
you don't know which kind your card requires, try just a plain ol modprobe 
with one and then do a "tail /var/log/messages" and see if it succeeded.  
If it didn't there will be an error and you can try the other.  (You'll 
need to be root to perform these commands)

If those tips don't work, you'll need to tell us about a bit more your USB 
Controller card (like what kind and model number is it :).
