The usb-storage driver emulates a SCSI drive, so you need the SCSI
drivers to access the drive.

Since this usb-ohci module inserted successfully, this means that you
have an OHCI USB host controller in your laptop. You can remove uhci
and usb-uhci from your script now that you know that you have an ohci.
However, another computer may not necessarily have an OHCI, so you
should use the original script if you are testing a different
computer.

Success so far.

It appears that your memory stick is not supported by the 2.2.16 USB
driver. The BL3.40 kernel supports about the same amount of USB
hardware as the drivers that I built for 2.2.16, so the memory likely
will not work with that kernel either. 2.4 has much better support for
USB storage devices, so you probably need to upgrade to at least Linux
kernel version 2.4.0 if you want to use your memory stick in Linux.
