korte,
These are just some random links and text I have from some research I did a while ago. The thing I was looking for was the ability to access a USB thumb drive as a regular drive letter from within DOS. Never tried it, but some of these report success.

I finally got it to work!! I have the following files on my boot disk:
himem.sys
ramrd.sys
usbaspi.sys
di1000dd.sys
And my config.sys is as follows:
dos=high, umb
lastdrive=z
device=himem.sys
device=ramfd.sys
devicehigh=usbaspi.sys /w /v
devicehigh=di1000dd.sys /dG
The file just above assigns my PNY 128MB thumb drive to the G: drive, and I can then access it through DOS. I don't have anything in my autoexec.bat file (don't really need it since I'm not accessing an external cd-rom.
not.
My device not disk drive. my device simple usb-rs232 physical converter.
korte,
You're welcome? ::)
Check the links I provided, some info links are there for, software giving providing information about connected devices, and drivers. Try it. The text was just from a .txt file I saved from a long time ago.
