USB module help

[Bob Hemus]

Back at the trough, again.  Displaying my ignernts agin.  I am trying to 
up-grade the gPhoto2 that came with my RH7.3 to gphoto2-2.1.1.  The 
manuel says to:

    'modprobe usb-uhci' goes OK, 'cause it's already there.  Then it 
says to 'modprobe usb-ohci' doesn't go OK.  Get this.

[root at localhost root]# modprobe usb-ohci
/lib/modules/2.4.18-3/kernel/drivers/usb/usb-ohci.o: init_module: No 
such device
Hint: insmod errors can be caused by incorrect module parameters, 
including invalid IO or IRQ parameters
/lib/modules/2.4.18-3/kernel/drivers/usb/usb-ohci.o: insmod 
/lib/modules/2.4.18-3/kernel/drivers/usb/usb-ohci.o failed
/lib/modules/2.4.18-3/kernel/drivers/usb/usb-ohci.o: insmod usb-ohci failed

When I did a  whereis usb-ohci, it just returns an usb-ohci
When I went to /lib/modules/2.4.18-3/kernel/drivers/usb/usb-ohci.o  It 
is there.  What do I need to do???  I know at least a dozen of you can 
point me in the right direction.  Thanks ahead of time.
