I'll admit that the hot-plug issue was a stopper for me. You'll have to use smaller devices <2GB because not many DOS ASPI clients understand FAT32 filesystems. ASPI is ASPI, no matter where it originates-there was, for a time, for example, ATASPI to work with ATAPI devices. If you can get USBASPI running, why not just use a DOS SCSI driver for ASPI, such as Adaptec's ASPIDISK? That should work. Oh, I don't think you're the only one certainly the topic has arisen here with regards to old DOS machines that don't even have USB ports. Others back in the day reported success with different tools, but I can't reproduce their success now.

However I've only found one driver, NJ32DISK.sys that will assign DOS drive letters for my thumb drives. I found a number of USBASPI.sys drivers, all seem to work to some extend, ie can see a Zip100 USB drive or a thumb drive. There was something called DUSE.exe that was supposed to be a driver package but I can't get that to work at all. Seem to have recovered the key items from it but curious if anyone has a copy of the original. I've found a slightly corrupted *.zip of some iomega usb drivers for DOS that I had never seen. Rather than make a long post I have created a web page with references and my nominal success: Not pushing or selling anything, just curious if anyone is still interested in this.

I think most of the world thought about it between 20 as the Win9x series came out which has adequate support for this.

I just got interesting in this general topic recently.
