<P>Hi,
<BR>
<P>I think the documentation (manpage of scanimage) is not got at
<BR>
the point, it does not explain at all how [DEVICE] looks like,
<BR>
it only tells you how you can get a list of available devices.
<BR>
<P>We also should change the output of scanimage -h:
<BR>
<P>-d, --device-name=DEVICE use a given scanner device
<BR>
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The format of DEVICE is backendname:devicefile (e.g. umax:/dev/scanner).
<BR>
<P>In the manpage of xscanimage it is described correct, the output of
<BR>
xscanimage -h also should be changed like for scanimage.
<BR>
<P>Henning, please would you add that to the TODO list?
<BR>
<P>Bye
<BR>
Oliver
