What am I doing wrong?

As a result of a virus attack in my computers boot sector I was unable to access files and emails through Windows and faced the long and tedious process of using DOS commands to recover these files.
This process proved very UNSATISFACTORY and time constraints forced me to give up and format my HDD.
I previously had noticed that my BIOS gave me the option of USB support for DOS so I enabled this option ( thinking that in future I could use my Memory Stick) and after REINSTALLING windows XP etc downloaded Duse.exe and followed the directions to load this in my floppy Boot Disk Config.sys file.
I have tried just about every option available for loading this as a device however the result is always that 2 USB Drive letters are installed but not their IRQ's and my memory stick is not recognised.Do you talk about using usb memory sticks with standalone DOS?

There are drivers. I THINK it was from philips. But there is no guarantee that they work with your memory stick.
(I failed with my sony memory stick.)
You need the usb driver and the harddisk driver.
Google a bit.
Try also the SEARCH in computing.net. There was a description at the standalone dos FORUM. (Not cmd in Windows!)

hope this helps

Update! :-/

Using usbaspi.sys from Panasonic in my boot config.sys my usb memory stick is found however no drive letter is allocated to enable it to be accessed???
