I have ubuntu 6.06 and an acer scanner. I have all the errors as described. When I setup snapscan.conf for the first time, xsane worked and I scanned an immage. After a reboot I have the libusb error message. Driver manager sees the scanner. As user no device . I see in man sane-usb it says as below. Ubuntu 6.06 has libusb0.1.4 Could this be the problem ???

LIBUSB SANE can only use libusb 0.1.6 or newer. It needs to be installed at build-time. Modern Linux distributions and other operating systems come with libusb. -- Detected scanner fails to load with "Invalid Argument" https://launchpad.net/bugs/24946 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
