I've gotten USB drive scanning to work in SEP based on the instructions in a previous post below. This works on unencrypted USB drives with no issues. However, if a USB drive is encrypted and then unlocked after it is mounted, it appears that the drive scan takes place. However, the total number of files that are scanned is 0. Has anyone gotten this to work on encrypted drives? If so, what did you end up modifying in the USBScan script that was put together by a Symantec SE? I've also noticed that even right-clicking and doing a manual scan on an unlocked USB drive does not scan any files either.
