We have a white list for approved devices. It works great for only allowing the approved Blu-Ray/DVD/CD burners, thumb drives, and USB floppy drives. If it is not on the appoved list the device is ejected, a message pops up "This USB device is not approved" and an email is sent to security. But if a external powered USB HD is plug in to the system LEM does not block it. The drive works. Can copy files to and from. Does LEM not treat external powered USB HD the same as thumb or burners? One of the drives that works with out being on the approved list is a Lacie Rugged Mobile Storage. i removed all devices from the approved list. Just to make sure I didn't have a typo that might allow the device. Doing this stopped the approved devices from working with the "This USB device is not approved" message. This verified that LEM is working with the exception of external powered USB HD.
Thanks for any help.
