hmm. i bet that is the culprit. i bet we should catch that eof, and run 
status anyway. instead of continuing. normally the 5120 is in blocking 
mode, and does not do this. even if we get the io error later to work, 
this will corrupt the image anyway, so it has to be fixed.

did you have the scanner connected to windows, then connect it to linux, 
without power cycling the scanner? if the windows driver sets up the 
scanner for some kind of non-blocking or buffering mode, this would 

if you power cycle the scanner while its connected to linux, does this 
happen still?
