USB FDD for 64HDD-PC

Hi!

I'm user of 64HDD Professional. I have for this one MS-DOS (7.10) computer.
I'm trying to use USB 3,5" FDD on this... Why 64HDD category? It's 64HDD computer.

What's my problem:

I added to config.sys driver usbaspi1.sys for detecting USB devices.

At starting computer is FDD found, but after are two errors:

ERROR: TARGET DEVICE NOT FOUND
ERROR: DRIVER RESIDES SINCE USB FDD WAS DETECTED

...and I was trying more PC-DOS forums, but everywhere is writting only about USB CDROM etc.

Can anybody help me which driver and how to install it for USB FDD as drive B: ?

Thank you for every answer.

Here's solution:

Add this line to config.sys:

device=c:\dos\usbaspi1.sys /v /u

I selected UHCI 'cause my DOS computer has only USB1.1,
if you have USB other version, here are parameters to replace /u:

/E (EHCI USB 2.0)
/O (OHCI USB 1.1 Add-on)
/U (UHCI USB 1.1 Integrated)

ignore errors:

ERROR: TARGET DEVICE NOT FOUND
ERROR: DRIVER RESIDES SINCE USB FDD WAS DETECTED

Please note that main floppy in computer marked as A: will be replaced with USB FDD, so will be not accessible.

I tried not to set this drive to B: - don't know how, can anybody help me?
