    Just to check all basics, have you done
    tail -f /var/log/messages

    and then plugged in the usb devices, that should tell you if the
    kernel is picking up the device and assigning it to an entry under
    /dev/

    Can you confirm that all machines are fully patched and uptodate? I'm
    sure you have gone through all the steps including checking
    /var/log/messages but its good to list out all the details so that
    false assumptions aren't being made.

    Its not clear from your mail whether your refering to the same usb
    devices being plugged into different machines and working on some and
    not on others or whether its different devices that were being plugged
    in to different machines.

    First one might indicate that there is a hardware problem with the usb
    adapters that the disks are being plugged into, guess what appears in
    the messages log might help identify this.

    If its the second one, the usb devices may not have the required
    entries under /etc/updfstab.conf.defaults in which cause you'll need
    to create a new file /etc/updfstab.conf.local and add the required
    entries to that and then include that file in /etc/updfstab.conf.
