    Hi,

    I have a HP5300C-Scanner, which should run (more or less) with the
    avision-backend-patch and the "usb-scsi"-patch for the kernel. After a view days
    hacking all the night and surfing the sane-webpages from my office-pc I decided to
    write to this mailinglist.

    My environment:
    Hardware: VIA-USB-chips
    kernel 2.4.1 for 686
     manually patched with the usb-scsi patch (patched Makefile,Config.in; added
     usb-scsi.h usb-scsi.c)
    sane 1.0.4
     manually patched with the avision patch for hp5300c
     copied the new libs (libsane-avision*) from /usr/local/lib/sane to
    /usr/lib/sane to use the directories the deb-package installed in.
    SCSI: all other modules disabled
    USB: removed module scanner
    /etc/sane.d/dll: only the avision backend activated
    /etc/sane.d/avision: scsi HP

    Now I get an entry in /proc/scsi/scsi which is definitifly my scanner, but
    xscanimage can not find any scanner and the hardware isn't responding at all.

    Onto my console and into my message-log I get the message:

      # tail -f /var/log/messages
      (...)
      Feb 13 19:39:37 ente kernel: usb_control/bulk_msg: timeout
      Feb 13 19:39:37 ente kernel: usb-scsi.c: write_scanner: NAK recieved.

    Perhaps my scanner is defect and I should bring it back. But it will be gone
    for a view weeks - and that's not so fine.

    I tested it also with win98. The results were 5 scanned pages - 30 tries to
    do that and 20 reboots, because of USB-locks. (I hate that virus)

    My 4 USB-ports work very fine under Linux (debian), but I get 3 stupid
    timeout-messages with cat /proc/bus/usb/devices (2 at list beginning and 1 at the
    end) - only with the scanner plugged (yes, it's powered on).

    Can anybody help me?
    Thanks
    Jörg
