[sane-devel] Canonscan N 650U LIDE Scanner does not scan but makes terrible noise

[Andrea Vai]

About the terrible noise... Gerhard (or others), do you need any more
testing from Winni and me? At the moment, a value of 0.76 for
dMaxMotorSpeed seems to be fine for both of us.

Winni, if you still have problems running sane as a non-privileged user,
try to read here:

http://www.sane-project.org/README.linux

and also
http://ubuntuforums.org/showthread.php?t=1565846&page=2&s=736558689cd343dc4c4af0d3cabe7a4e(last
post)

and here: http://manpages.ubuntu.com/manpages/hardy/man5/sane-usb.5.html(LIBUSB
section)

and also, maybe, here:
https://help.ubuntu.com/community/ScanningHowTo#Permission_Issues

or simply among here ;-) :

Best regards,
