    ! PLEASE CC to me i'am not registered to this list

    i'll try to use the usb-storage with my Sony DSC
    but since kernel version 2.4.7 it's seems to be brocken.

    look like a problem with the interrupt handling with the
    usb-uhci which shares it's interupt with the sym53c8xx driver.

    i use a 'dualhead' SCSI controller from DIGIAL with
    two 53c875 chipset.

    any idea?

    cheers
