   I can find a post dated 2002 discussing that scanner.   
      
   If I had to guess, the config space of the scanner reports it is   
   USB2, while the hardware is actually USB1.1 . It's possible the OSes   
   of the time were working, but didn't have enough "quirks" coded   
   to make a robust driver. The scanner may be fibbing about what it is,   
   over USB.

   If the hardware design is bugged on the scanner, you might need   
   real/actual USB1.1 ports on a computer to test it. The designs   
   that had a NEC USB2 chip (early USB2 era) would still have   
   USB1.1 ports on the Southbridge to use.   
      
   I do have a piece of junk in the junk room for this. I have   
   a new in box Opti 82C861 USB1.1 chip with two USB connectors (white tab),   
   and that has a PCI edge connector on it. It only has one slot cut   
   instead of two slots (I'll have to look that up). So if I want genuine USB1.1   
   ports with no possibility of USB2.0 interpretation, I can have it :-)   
   The card cost me $49 back in the day. The plan was possibly "if the   
   USB 1.1 ports on this pig are ESD-ruined, what then". It was a spare.   
   I have a ten year old PC that still has a PCI slot.
