I also got this UIO error sometimes here on my linuxboxes, but they don't
seem to disturb. Well in the meantime, I tried to figure out, when this
UIO error occurs. In the end it only occurs during power-up of the scanner,
directly after pluging it in. So I did some changes to the setup procedure
and managed to make these UIO errors disappear on my boxes.

Could you please checkout the latest CVS stuff and test on your OS/2 box?
