You probably can get it to work. If the Linux team cna, then the code can be ported as drivers to DOS. Problem is that really good USB support in Linux is fairly recent and it may take a while.
The guys over at
www.freedos.org have USB support up. I'm not sure about USB Mass Storage (flash drive) support though. The code exists in the open source world, it's jsut a matter of porting it to DOS.
Might also be interested in reading this:
http://www.informationweek.com/story/IWK20021003S0007
explains some things about USB in DOS, even ouches a bit on mass storage devices.
BTW, have you tried the DUSE drivers? They might work (they mention storage media in the description, and sites say they work with more than poketec products):
