    Anyone get this thing working with USB? It's driving me nuts. I think it's
    configured correctly, but scanimage segfaults. Below is the last part of the
    strace for scanimage, and hopefully it will help someone know what's going on
    here.

    Config info:

    [root@eclipse /dev]# l *scanner
    lrwxrwxrwx 1 root root 10 May 4 20:41 scanner -> usbscanner
    crw-rw-rw- 1 root root 180, 48 May 4 19:54 usbscanner

    [root@eclipse /dev]# cat /etc/sane.d/hp.conf
    /dev/usbscanner
    option connect-device

    My kernel is the Red Hat 7.1 kernel, which is 2.4.2+"bugfixes". I have the
    usbcore, usb-uhci, and scanner modules loaded. The kernel does see the
    scanner and it shows up in usbview, however one strange thing is that reading
    the list of SCSI devices (with usbview or by catting /proc/bus/usb/devices)
    is VERY slow whenever the scanner is plugged in. Like, it takes 10-20
    seconds. When the scanner is not plugged in, it's instantaneous. My SanDisk
    SDDR-31 USB CompactFlash reader works great, and there is no delay accessing
    info while it is plugged in without the scanner.

    Also, the sample program in the scanner.txt file in the kernel does seem to
    work, but it also takes a long time before the scanning starts.

    I've tried SANE versions 1.0.3 shipped with Ximian GNOME and 1.0.4 compiled
    from source. Both do the same thing.

    [micah@eclipse micah]$ strace scanimage -L
    [...]
    open("/proc/sys/kernel/sg-big-buff", O_RDONLY) = -1 ENOENT (No such file or
    directory)
    open("/dev/scanner", O_RDWR|O_EXCL) = 6
    ioctl(6, TIOCSCCINI, 0xbfffe254) = -1 ENOTTY (Inappropriate ioctl for
    device)
    ioctl(6, TIOCGKISS, 0x401dead0) = -1 ENOTTY (Inappropriate ioctl for
    device)
    brk(0x8055000) = 0x8055000
    brk(0x805a000) = 0x805a000
    rt_sigprocmask(SIG_BLOCK, ~[], [], 8) = 0
    rt_sigprocmask(SIG_SETMASK, [], NULL, 8) = 0
    rt_sigprocmask(SIG_BLOCK, ~[], [], 8) = 0
    write(6, "*\0\0\0)\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0"..., 42) = 42
    rt_sigprocmask(SIG_SETMASK, [], NULL, 8) = 0
    select(7, [6], NULL, NULL, NULL) = 1 (in [6])
    rt_sigprocmask(SIG_BLOCK, ~[], [], 8) = 0
    read(6, "", 41) = 0
    rt_sigprocmask(SIG_SETMASK, [], NULL, 8) = 0
    --- SIGSEGV (Segmentation fault) ---
    +++ killed by SIGSEGV +++

    Notice the "inappropriate ioctl for device" messages. That indicates to me
    that there's a bug in scanimage.

    Any ideas? Anything else I can do to try to debug this? Is there a hardware
    problem?

    Finally, does anyone know a way to convert the "out.dat" file that the
    example in the kernel source produces into something useful? It would sure
    be nice to get some scans in right now.

    Thanks!
    Micah
