You can use usbaspi.sys together with nj32disk.sys. Add these to CONFIG.SYS and it should work with FAT16 USB storage. Works for me in MS-DOS mode on Windows 95, so it should also work with DOS 6.22.

Yes actually, one of his utilities revealed that my USB controller is UHCI, which doesn't seem to be compatible.

You sure of that? because the documentation actually states that UHCI (made by intel and VIA) is the *only"compatible controller so far.

Mine uses an SiS chip, maybe that was the reason.

I found a video on Youtube showing how to install a driver using one of the methods I tried before, but it's still not working for me.

It seems he only adds two of the three files copied to the C: drive to CONFIG.SYS, and they seem to load on my machine, but they don't see my USB drive.

Do I need to do something with the DI1000DD.SYS file too?

As not all drivers works with all computers, I'd try to try either:
- The boot disk from Puppy Linux.
- Hiren's Boot CD.

They include plenty of drivers, and menu driven selection of drivers. So, you can boot from one of those and try one by one every driver until you found which one will work with your hardware. Then, look into CONFIG.SYS/AUTOEXEC.BAT to see how is it loaded and try it on your hard disk.

Check if your motherboard BIOS support USB legacy mode. You don't need any 3rd-party drivers for USB in DOS if the motherboard BIOS support USB legacy mode and you are using the USB controllers from the chipsets.

Legacy mode is for keyboard and mouse only, which appear as ps/2 devices then.

Sometimes yes, but not necessarily/not only.

E.g. contrary to the above with this board 'Legacy USB Support' also refers to USB Mass Storage Devices. If you disable 'Legacy USB Support' USB drives are also disabled and you cannot even boot from them:

Actually if you can boot from USB drives then your BIOS supports USB Mass storage devices as regular drives and no further drivers required regardless of OS. You only have to make sure that used file system is supported by your OS (in case of DOS it's FAT16/32).
