Not necessarily. It might just fail to meet the timing specification the
controller is demanding.
A similar effect occured with my scanner attached to a adaptec
controller. BTW, which brand is your controller?

You might want to try whether the following is working - within the
computers BIOS setup disable both external and internal caching
temporarily. This makes the system extremely sloooooooooooow - but it
made my scanner working. (That's no solution, of course! -- Just a
way to trace the problem.)
