gPhoto2 kernel problems

[Bob Hemus]

I'm running RH 7.3 2.4.18 kernel.  The gPhoto2 Manual says that RH 7.3 
will run gPhoto2. when I do:
        [root at localhost root]# modprobe usb-uhci
        [ root at localhost root]# modprobe usb ohci
            modprobe: Can't locate module ohci
        [root at localhost root]# mount -t usbdevsf usb /proc/bus/usb
            mount: fs type usbdevsf not supported by kernel
[root at localhost root]#
This is what I get.  Do I need to patch the kernel up to 2.4.19 to get 
gphoto2 to work?
If so I guess all my problems (well not quite all) will be solved?
