    Hello.
    I did check the archive for this problem and some people said it had
    worked after but..
    I did patch linux-2.4.0 aha152x driver with this :

    I used rpm packages from redhat fisher 7.1beta (aka sane-1.0.3-10 and
    xsane-0.62-4). xsane find the device, but when i try to acquire a
    preview, lots of "(scsi0:2:0) no buffers left for 128(128) bytes (data
    overrun!?)" appears in dmesg command..

    I don't know how to make work this scanner anymore since if i reboot in
    2.2.1x kernel there's no problems. Could you please help me ?
