Is there a usb driver needed for windows98 to use an acer acerscan 320u flatbed scanner and if so where can I get it?

Windows 98 needs a USB driver. Try downloading one from the ACER WEB site for your model scanner.
OR you can try these WEB sites ;-

I have an old Mirascan v3.04 620UT flatbed scanner (windows 98)

There is no Vista driver for this Acer scanner.
Acer didn't create a vista driver for it. (or Benq)

FlatbedScaner5 ="Acer scanner 310U/620U" FlatbedScaner13="Acer 320U/340U/620U+/640U" FlatbedScaner16="Acer scanner 620UT+/640UT" FlatbedScaner19="Acer scanner 1240UT/5100U" FlatbedScaner20="Acer scanner 640BT/640BU" FlatbedScaner21="Acer scanner 4300U/3300U" FlatbedScaner23="Acer scanner 4300U/3300U"
The driver package includes the following files with file sizes ahead.
108,032 acerscad.dll 3,269 acerscan.inf 24,192 ksthunk.sys 451 Model.ini 17,683 sti.inf 30,663 u126v041.bin 30,598 u176v040.bin 32,301 u190v041.bin 31,664 u192v073.bin 30,221 u222V065.bin 27,984 u34v110.bin 31,364 u64v119.bin 31,048 u96v121.bin 27,648 usbscan.sys
All these files are derived from those on Windows XP64. Maybe it works on Vista 32.

Running windows vista os

Afraid not Scanners made ror Win95/98/Me run to DOS commands
XP/Vista of course are both NTFS systems and will not speak to such a scanner.
Time for a new scanner Vista Compatible.
