nj32disk-v1.06.zip NJ32DISK.SYS is the ASPI disk driver for USB mass-storage devices (it assigns a DOS drive letter). Run the USB hardware driver (such as USBASPI.SYS) before NJ32DISK (similar to the way you first run the cd-rom ASPI driver before running MSCDEX). If USBASPI does not find any USB mass-storage devices on bootup, NJ32DISK will not load or assign any drive letters. Drive letters assigned will come after the internal Floppy drive, Hard drive, and other bios established storage devices have been assigned drive letters.

usbdos.zip This is a DOS USB driver package. There are several programs here that will allow you to use USB keyboards, mice, joysticks, printers, and disk drives in DOS. These programs work VERY differently than any of the DOS USB drivers you have seen before, and will allow you to use USB devices in ways you probably never even imagined possible until now.
