Subject: libsane: sane programs don't work if not root Package: libsane Version: 1.0.19-22 Severity: important
*** Please type your report below this line *** I have a Lenovo 3000 N200 laptop with an integrated webcam (which works through v4l). SANE programs (e.g. xsane) fail to make me use any scanner giving an error related to the webcam, like scanimage: open of device v4l:/dev/video0 failed: Invalid argument sane-find-scanner reports: found USB scanner (vendor=0x04b8, product=0x010c) at libusb:006:002 found USB scanner (vendor=0x08ff, product=0x2580) at libusb:002:002 (btw ignoring the webcam) If I run scanimage from sudo, I can use the scanner without any problem. I don't know how to address this problem, which looks like a "permission" issue. I'll send also the output of SANE_DEBUG=255 USB_DEBUG=255 scanimage -L as attachment.
