How can I make the USB Devices?

[SEan Strand]

Hi-Ho, am running i386on an HP Pavilion t3345.uk amd machine.
When I first loaded this machine it would mount my IOMega drives - no
problems.
Now, since I recompiled the kernel it will not make the devices. So I
reloaded and remake the filesystems.
So How do I re-make the usb devices, so I can mount the external IOMega
drives?

Oh there are no reported controllers working, but this is being typed from a
wireless usb keyboard and mouse.
Any help would be most welcome,

Thanks and regard SEanS
