I only have very limited info on this.  I don't know if it 
would help, but most if not all of the backup software programs 
allow for USB support for backing up and restoring a drive 
image.  I've done this before with programs like Norton Ghost. 
They use something like I think it's called "PC-DOS", which is 
in what the HD's image is restored, and it can used to restore 
the image from an external USB drive.  So that allows USB use 
in (a manner of speaking) DOS.

I believe for this to happen in any scenario, the mobo's BIOS 
would need something like "Legacy USB support" which (in 
addition to allowing USB 1.1) allows the mobo's USB ports to 
work outside of Windows.  I have to enable that in my BIOS to 
use external USB HD enclosures outside of Windows.  But if a 
mobo does not have that in its BIOS, that doesn't mean it won't 
work, it could generally mean Legacy USB support is always 
enabled.

Look at this, USB support in DOS:

http://www.georgpotthast.de/usb/

That last link has a "Download" link AND an "Order" link, so I 
don't know if the download is limited or what.  The download is 
http://www.georgpotthast.de/usb/dosusbd.zip .

Here's some more links, this one talks about what I mentioned 
about Legacy USB: http://www.toolsthatwork.com/bbdocs/usb.htm
This one mentions PC DOS used by Ghost:

And "Yes, there are USB drivers for DOS..." which may be what 
you've already found:

Is there anyone on this list who has actually managed to get
USB support to work in DOS?  I've done a lot of searching and
found a lot of different methods that supposedly makes USB
ports accessible in DOS.  I've tried a couple of them with no
success.  I'm not interested in third party knowledge, but
only interested in someone who has really been able to do it.

Sorry if I sound harsh or ungrateful for help from this list
but I'm getting too old to go on a wild goose chase.  That's
why I am looking for firsthand information on the subject.

Thanks,

Tom
