[sane-devel] umax1220u: sane_start: Invalid argument

| You could try to get a debug log of the backend in operation:
| 
| SANE_DEBUG_UMAX1220U=255 scanimage 2>error.log

Thanks.  That seems to give useful information.  Not that I know how
to interpet it.

Near the end, just before the error message, the
UMAX_set_scan_parameters don't look reasonable to me.  Are the
resolutions DPI?  If so, they seem low.  Is it OK to have so many of
the other parameters 0?

Do you see what is causing the diagnostic?

| you might also try a 32 bit system just to see if that is it...

I booted from a Ubuntu 8.10 i386 live CD.  The diagnostic and the
debug output looked similar.

Thanks again.
