Help! Someone Please Help! I've got 16 PC's running 6.22 DOS and none of them have floppy drives. They used a proprietary FDD plug in that are missing/broken and Acrosser can't cough up replacements. The Mobo does have 2 USB 1.1 headers that run on a UHCI protocol. I bought me some USB adapters and pluged them in. I confirmed they work thru a win98 app on a 'host' hard-drive that I trade out. I tried all the USBASPIx files I could find, MHairu, DUCE, DATOPTIC, my heads spinning after a week of this. I always seem to end up with 'TARGET USB DEVICE NOT FOUND or ASPI MANAGER NOT INSTALLED or DOS IN PROTECTED MODE. ARRRGGG!!! I finally tried DOSUHCI from a guy over in Germany and I got a lot better results. It finds the floppy drive and even sets it up a drive letter that I can go to but I can't do a DIR command without it locking up. The program that he wrote includes USBVIEW.exe which works and shows me all the info of the floppy drive. It also includes FLOPPY.exe which works and gets the floppy drive to post info about the disk it carries (always says NAK though). I'm at my wits end with this thing and I've got to have a removeable media solution thats cheap for these 16 PC's. I'm having to move programs on them by physically removing the hard-drive and using a host PC. Its quite a drag. Thanks!

I did those options first but they are geared toward CD drive compatibility and don't really go into Floppys. I found a guy named Georg Potthast who has a website thats awesome with info on just about anything. I emailed him and he said that I'll probably never get a USB floppy drive to work because the different manufactures do differently for thier drivers and communications over UHCI or OHCI. I'd have to make a custom driver to run the floppy drives and well, I program robots and PLCs not drivers.

From his letter:
"Floppies use a different protocol over the USB link than flash disks. So a driver for a flash disk will not work with these. It may be that the latest USB floppy drives have moved away from the specification and also support the same protocol as flash disks but I have not seen this yet."

He advised since I set up the USB on the MOBO, I should just go ahead and use flash drives since his code is geared for them and the manufacturers generally share the same protocols. Makes sense. He said his programs can handle up to 4gig sticks as long as they don't use onboard firmware (U3). Finding that type is getting rarer every day but its not too late :)

If you don't need to boot from those floppies then find one PC
with a floppy in it and use 'InterServ' to turn it into one which
one out of those 16 PCs can access via 'InterLink' as if it were
a normal drive...

aCROSSER website wasn't much help for me. Can you find support for your machine there?

The solution from Bicephale has worked for me to transfer files on many "weird" DOS machines; especially those with no floppy or cd or usb.

I even called Acrosser. They weren't any help at all. If I could have gotten replacement floppy drive cables that would have been great. Thier board uses a 1/2 size proprietary floppy cable header. It makes for a very small and brittle connector. They got a standard size IDE header though and two USB headers. Why skimp on the floppy? I've ordered around 6 USB flash drives to try out. They are the older gen with no firmware onboard. Hopefully one works. I can't really run cables because these are spread out, I've got to have a removeable media. The Corp IT department attempted several times to get ethernet working as the MOBO supports IP addressing. They just couldn't get it to fly.

I understand the cabling problem. I've programed stuff over a 100' serial cable and you could almost see the information move back and forth.

Do these have a parallel port and, if so, have you tried to use a parallel port floppy? Please note this is a shot in the dark; some proprietary machines (like Itronix) will only recognize one particular parallel port floppy drive and not work with dozens of others.

Might be worth a try though?
