I scream over USB device under DOS because they won't work!

USB is surely a great invention, an industry standard that let all device connected to the PC with an USB connector, and if you got too many devices, just add an USB hub. An USB hub only about US 8, isn't it cheap and easy?

When you dealing with GHOST, or simpily want to backup a large amount of data in FAT32 partition, you'll found that working in DOS environment is the best, no locked files, no screen savers, no fancy animations ... but USB device won't work because BIOS too old!

It's possible to let USB work under DOS, some guides and drivers scattered on the Internet. I spent a lot of time testing them, and found that DUSE (from Cypress), USBASPI (from Panasonic and Iomega), and DI1000DD (from Novac) can really let USB hard disk, finger flash disk and USB CD-ROM work ... but of course with some kind of limitation, it heavily depends on the chipset and BIOS. For example: DUSE work on device with Cypress chipset only, some BIOS didn't like USBASPI, then it'll hide the USB device from the USBASPI.

I've collected some working drivers and put them on floppy disk (also thanks to contributor Bernd Blaauw, Robert Riebisch and Mike Treu). For others don't know how to setup those drivers properly.

** Notice:

[1] These USB Drivers only work for storage device like Flash Disk, USB hard disk or USB CD-ROM, device such as Mouse or Printer were not supported.

[2] During my research of GHOST a Serial-ATA hard disk to USB hard disk, I found 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!
