If it works using the Twain driver then there probably isn't a problem 
with interrupts or DMA.

I am not sure what you mean by "works direct". All scanners require
driver software but for common scanners this is often included in the
application software. I would expect that there is an error in the
configuration of that driver or that it does not support this particular
scanner.
