Sandisk USB CF reader and 2.4.18; usb-storage bug?

[Dylan Griffiths]

Two problems here.  The first is that even after poking in SCSI's core, 
modprobing usb-storage hangs and is unkillable:

Module                  Size  Used by
usb-storage            53360   2  (initializing)
...
scsi_mod               83376   3  [usb-storage sd_mod sg]
...
usbcore                49088   1  [usb-storage dc2xx hid uhci]

The dmesg (w/ verbose) looks like this:

SCSI subsystem driver Revision: 1.00

Bug or no?  It never finishes initialization, and never wakes up, and 
/dev/sda never works properly.
SCSI reads:

/proc/scsi$ cat scsi
Attached devices:
Host: scsi0 Channel: 00 Id: 00 Lun: 00
   Vendor:          Model:                  Rev:

Note: Please CC me as I'm not on the list..

Try sending this to the usb-storage maintainer, he should be able to
help you out.
