Why? You can just insmod them directly.

Err! Why are you rebooting? The point of making them as modules is
that you can load (insmod or modprobe) or unload (rmmod) them at
run-time without having to reboot.

But, did you check if the modules were loaded? Can you post lsmod output?
Also remember that SCSI Primary Commands-2 (SPC-2) specification, and
SCSI Block Commands ? 2 (SBC-2) commands are used by USB, and Linux
USB subsystem follows *SCSI emulation* for communication with mass
storage devices.

Because usb_storage module is used:

You should have mentioned how you loaded the module, and what
output/error message you got. As mentioned earlier, check and post
lsmod output.

The module that it "depends" on hasn't been enabled (BLOCK) in the
configuration, perhaps?
