Try putting your scanner at the end of the chain, and using a real
terminator (not the built in one). This is the only way I could get my bus
working w/ the scanjet attached.
I think the scanjet's have some sort of coin-flipping mechanism in them to
decide whether or not to terminate the bus... A real terminator makes this
problem go away :)
