One of the modules is the same for both - scsi_mod.  So you cannot insert 
it twice.  Which particular USB-storage module refused to load - scsi_mod 
itself, or sd_mod, or the three usb modules?

USB storage devices are scsi devices, that is why you insmod scsi_mod and 
sd_mod before usb-storage.  If you need to insert the USB modules first, 
they will get the first SCSI address (0,0,0).
