I wondered if you could help. I am trying to enable a USB Safecom Technologies 5.25 Disk Caddy in DOS (Maxtor 20GB Hard Drive). The hard drive has been formatted with 8GB FAT32 Partition. I have used USB dos drivers and DUSE in the past to load USB CD/DVD drives in DOS which have worked. Unfortunately I can not get the Caddy to function in DOS. I have tried all of the mentioned options on http://newdos.yginfo.net/usbdos.htm. DUSE 4.2 will enable the USB port but will not seem to have a compatible driver. Popup message reads driver not loaded. DUSE 4.9 Hangs. I also tried USBASPI.sys. I have a version that does recognise the maxtor drive and does not hang, it see's the drive on ID 0. This is great but I can not find a universal SCSI driver to make it work correctly. I have tried both DI1000DD.sys and ASPIDISK.SYS. Both of these hang when loaded. I have tried DUSE4.2 using a USB CD drive on the same PC, and this works fine, so I know the PC can utilise USB ports in DOS. I have also tried the DAT.exe boot disk, with no success.(http://www.datoptic.com/Drivers/DAT.exe) Have you any Ideas why the USB mass storage device (safecom caddy) will not function with all the universal drivers? Thanks

Hi, What version of DOS? Have you tried: USBASPI1.SYS /v ? M2 If at first you don't succeed, you're about average.

I am using USBASPI5.SYS /v /w. This is showing the mactor drive with ID 0. It is showing all the controllers and seems to be working. I have tried this with Dos6.22 and win98SE startup disk. If I habe nothing else in the config.sys or autoexec.bat the PC shows the information on the USB ports then returns to the A prompt. As soon as I try and load one of the universal drivers after USBASPI5.sys the system hangs when trying to load. Thanks

I still see that you are evading telling us what version of 'dos'. If you formatted your hard drive in FAT32 (W98 8GB) you won't see it using FAT16 (DOS6.22). There are no universal drivers.

"As soon as I try and load one of the universal drivers after USBASPI5.sys the system hangs when trying to load." What drivers? M2 If at first you don't succeed, you're about average.

as mentioned in an earlier post. I have used both a dos 6.22 startup disk and win98 startup disk. If using USBASPI.sys. another driver must be used to assign the port to the hard drive. In most cases one other posts is seems that people have used DI1000dd.sys or ASPIDISK.SYS (these are the universal SCSi drivers) After writing the first post I thougth that the FAT32 might be a problem so I have reformated the drive to FAT 1.5GB Partition. Thanks

I use these in w98se DOS: aoatapi.sys /D:oemcd001 USBASPI1.SYS /v DI1000DD.SYS You can leave out the first one if you don't need CD access. M2 If at first you don't succeed, you're about average.
