No, that did not help.
I still cannot use the 2.2.26 modules in BL2.1, they act like they are not 
there, so I put them into BL3.32 and tried again.

It looks like things are going okay until I insmod usb-storage and get 
(three times):  bus_reset() requested but not implemented
USB Mass Storage support registered.  (Unlike 2.4.31 where there is also 
something about sda and sda1).

I did some HOWTO reading and looked in /proc:
/proc/scsi/usb/0  (or in 2.4.31 /proc/scsi/usb-storage-0/0
Host scsi0: usb-storage
Vendor:  unknown
Product:  USB Flash Disk
Serial Number: None
Protocol:  Transparent SCSI
Transport:  BULK
GUID:  113098000000000000000000000000

So 2.2.26 did find the Flash Disk.

But the two kernels differ in other files:
The above info  did not get to where it was supposed to in /proc.

/proc/scsi/scsi

2.2.26
Attached devices:  none

2.4.31
Attached devices:
        Host:  scsi0    Channel ...... ID:   Lun:
        Vendor  Model   Rev
        Type    ANSI   (all filled in with info)

/proc/partitions
2.2.26
- hda and hdb and subpartitions of them
2.4.31
also 8 0 64464 sda and 8 1 64208 sda1

/proc/devices
2.2.26 - 
2.4.31 - also  Block devices 65 sd and 66 sd


Can I manually edit the files in /proc to match 2.4.31 so that I can mount 
/dev/sda1?  I don't want to risk it in case I mess things up badly.

Some of the crashes I sometimes got were from insmodding scsi_mod and 
sd_mod after booting with a kernel that had them built in.

I wonder how the guy with the Olympus camera got it working with 2.2.18.

Would it help if David compiled a 2.2.26 USB-storage kernel using a config 
similar to his that worked?  Using the same gcc etc.
