Not sure if related to everyone else ... I get the grinding sometimes with scanimage and everytime with scanimage -T when using an older usb cable ... I remembered that my N650U came with a translucent usb cable that I could see the shielding and had a magnetic filter on both ends. After installing the usb cable that came with the scanner I haven't had the grinding issue once ...
Wondering does the SANE version 1.0.15 use a slower usb mode ? or less aggresive settings that work with a usb cable that isn't properly shielded or rated for faster USB ? Anyway that is my 2cents ... good luck Ubuntu 10.10 64bit / libsane 1.0.21-2ubuntu2 / CanoScan N650U as device plustek:libusb:00x:00x / 04a9:2206 Chip=LM9832/3 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/83957 Title: Cracking noise on Canon lide30, possibility for hardware failure -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
