I did. I just rebooted and tried it again too! That puts me in mind, is
there anything I could maybe pass via lilo to the kernel?

Only that it is not claimed by any active driver. I would have thought that
the kernel patch would be designed to cope with this anyway. The driver also
requires some support files taken from windows, which I assume also factor
into supporting this. The thing about endpoints is completely meaningless to
me, I'm afraid! Somehow I think I am going to learn anyway.... :-)
Is it possible that the scanner is faulty? In such a way that it will work
with windows but not with Linux? The twain driver for the scanner crashes
annoyingly often. I have had the same problem with a serial port once on a
different machine (working in win but not lin, that is to say).
