What type of USB storage device are you using?
This kernel obviously cannot recognize it on your computer.

Please try it also with David's 2.4.31 kernel and modules, posted at 
http://keesan.freeshell.org/bl/2.4.31 - bzImage.431.gz (gunzip it first) 
and the modules are in userspec.tgz.431 - remove the '431', unpack it in 
/tmp, and just copy over the modules: usbcore.o usb-ohci.o and usb-storage 
to /lib/modules/2.4.31/misc (make that directory and subdirectory).
The modules are in various subdirectories:

2.4.31/kernel/drivers/usb/usbcore.o
......../usb/host/uhci.o
and ..../usb/storage/usb-storage.o

If anyone wants I can package these three drivers in a .tgz and post them 
at my site, to install into /lib/modules/2.4.31/misc, if you only want to 
try David's big kernel with USB storage.

This kernel has built-in scsi, no need for scsi_mod and sd_mod.
loadlin bzimage.431 root=/dev/XXXX ro

You can instead try David's 1-floppy USB boot disk, which you can download 
and write to a boot floppy disk (make sure it is 100% good first, by 
formatting in DOS).  Get it from:
http://keesan.freeshell.org/usbfloppy/linux-usb.tar.gz
Contains the 1440.img disk image and some other things (I forget what).
dd if=1440.img of=/dev/fd0

Hit 'Enter' after you see a line about sda1 to get the prompt back.

I recall that David's first few attempts at a 2.4.31 USB storage kernel 
worked with several devices but not my Olympus smartmedia card reader, 
until he changed something in kernel configuration.  Maybe the 2.2.26 
kernel could be fixed to work with more storage devices the same way?

Thanks a lot for your help, Sheldon.

After getting some sleep, I checked out the situation more carefully with 
our memory stick and card reader.  The stick works in DOS and with David's 
two USB kernels, perfectly.  The card reader mounts (if it is plugged in 
all the way, otherwise won't accept an address) with the message:  Found 
FlashCard..... PBA D351 has no logical mapping;  reserved area 
FFFFFFFF.... Bad LBA... for block  ....(19 lines of this).  Despite the 
long error message it is quite usable and online research suggests (to me)
something to do with a buggy driver for Sandisk Smartmedia card reader.

I had to be careful to use David's modules and not the ones I had compiled 
for my 2.4.31 kernel.  Sometimes they are interchangeable but not here, 
which would imply there is a major difference between our USB setups.

My kernel does not work even with the stick. uhci or usb-uhci crash it 
after  'USB UHCI at I/O 0xef80, IRQ 11'.  Back to the drawing 
board.  (Something at some point was assigned IRQ 9 - maybe it depends 
what IRQs have been used by other devices first).

David, any ideas where I went wrong in my config?

Do you have onboard USB?  We were given two loose ASUS P5AB boards and put 
in add-on USB cards, and I don't think we had USB headers on the boards. 
Our add-on cards are mostly ohci, our onboard USB is uhci except for 
Compaq.  David's kernel worked with both for us.  Have you successfully 
used USB on this computer with any device and OS?

I have never install BL2.1 to loop - is it difficult?

It does NOT support USB storage, I checked the config, don't try it.
USB is not mentioned in the config for the big kernel, don't know why, but 
since Steven provided the modules for it he must have compiled for it.
