look at the man pages for modules.conf (or google for the man pages)
in my system, since I don't have usb stuff compiled in statically, here
are the relevant lines in /etc/modules.conf:

alias usb-interface usb-uhci 

The hotplugging scripts (again, google for them and see what docs you
can find) _should_ take care of loading up usb-storage AND scsi_mod

At that point, you be able to fdisk or mount /dev/sda (or sdb, depending
on if you already have scsi or scsi emulated devices on your system). 

I use CompactFlash cards through a usb-dongle on a daily basis. Word of
the wise: Make sure your kernel is fairly current! I have troubles with
USB and CF cards on anything less than a 2.4.19...though it does work
well on a Mandrake 8.2 2.4.18 kernel. 
Somehow, with a stock 2.4.19, i have little trouble, though my co-worker
still has a heap of trouble on his machine. 
Hopefully a stable 2.6.x kernel will have better USB support
