    Hello,

    I have a NEC VERSA 6060 laptop with an Adaptec SlimSCSI 1460 PCMCIA SCSI card.
    It works ok with SCSI disc drives, but the scanner is not working. Generic
    SCSI support is a module. These commands are typed from root.

    I appreciate any suggestions, thanks, -Dave.

    This is in dmesg (note that the model is reported as C1100A instead of C5100A;
    does the hp backend care about that?):

    aha152x: processing commandline: ok

    synchronous=disabled, delay=100, extended translation=disabled
    aha152x: trying software interrupt, ok.
