There were problems I have been working on and have gotten Xsane to work <br>
now. It came down to installing the package libusb-0.1.so.4 .<br>

# scanimage -L<br>
device `brother3:bus4;dev2' is a Brother MFC-295CN USB scanner<br>
<br>
So I have a question now though. When launching Xsane GUI the <br>
application window opens very small and cannot be resized in it's <br>
Konsole window then. I must then move Xsane application and preview <br>
windows to another workspace where then the application menu show up <br>
legibly. Using KDE Plasma with Wayland for the Desktop Environment. Can <br>
this issue be debugged and fixed?<br>
<br>
Here is a screenshot of what I am describing :< <a href="https://ibb.co/YTcF9DrB" rel="noreferrer" target="_blank">https://ibb.co/YTcF9DrB</a><br>
<br>
There is also an openSUSE Forums thread which I opened here :< <br>
<a href="https://forums.opensuse.org/t/brother-mfc-295cn-network-connected-printer-fails-to-scan/191648/70" rel="noreferrer" target="_blank">https://forums.opensuse.org/t/brother-mfc-295cn-network-connected-printer-fails-to-scan/191648/70</a> <br>
<br>
This led to the final ability for Xsane able to scan and detect the <br>
MFC-295CN scanner.<br>
<br>
Thanks<br>
