I don't understand. The device in question breaks when we try to read
a page that it reported it supports? we did do
        /* Ask for all the pages supported by this device */
        result = scsi_vpd_inquiry(sdev, buf, 0, 255);
        if (result)
                goto fail;
Didn't we? Are we checking that 0xB0 or 0xB1 are returned?
