To the best of my knowledge there are only 2 drivers. This is what I have in my CONFIG.SYS:
CODE
[USB]
device=Boot\emm386.exe noems
device=Boot\USB\USBASPI.SYS
device=Boot\USB\Di1000dd.SYS
; A limitation of the DI1000DD.SYS (NOVAC), it only support FAT16 format!
; If you format your USB connected hard disk with FAT32, it shows nothing when you type DIR,
; when you try to FORMAT it, the PC will crash!
