usb mass storage problem

[Patrick Hsieh <pahud@pahud.net>]

Hello list,

I have a usb external storage device within IBM 2.5" 6GB IDE.
I'd like my linux 2.4.13 to recognize it. So I compile kernel with USB
support as well as:

1. Preliminary USB device filesystem
2. UHCI support
3. USB Mass Storage support
4. USB Human Interface Device support


I've read the usb guide from
http://www.linux-usb.org/USB-guide/book1.html

then I mount -t usbdevfs none /proc/bus/usb

debian:/proc/bus/usb# mroe devices
bash: mroe: command not found
debian:/proc/bus/usb# more devices

Seems kernel recognizes the usb-storage device. Then I check /proc/scsi

debian:/proc/scsi# ls
ide-scsi  scsi  usb-storage-0

debian:/proc/scsi# cat usb-storage-0/1
   Host scsi1: usb-storage
       Vendor: Unknown
      Product: USB TO IDE
Serial Number: None
     Protocol: Transparent SCSI
    Transport: Bulk
         GUID: 05e307000000000000000000
     Attached: Yes




Well, all seems fine! But how can I fdisk the usb storage device and
repartition it?

It doesn't mapping to /dev/sda /dev/sdb /dev/sdc


Idea?

Thanks.
