Endpoint Encryption

We are trying to roll out SEE 7.0.7 to our new HP EliteBook 8440p laptops.  During the pre-boot authentication screen, the external peripherals go dark and do not work.  Integrated touchpad and keyboard work fine.  This also happens when the laptop is connected to the docking station (and is where the real issue/inconvenience lies).  I have enabled legacy USB in the BIOS in an attempt to address, but have been unsuccessful.  Has anyone else been faced with this issue?  I have already opened a tech-support case, but wanted to check here as well.

After posting this I noticed that 7.0.8 is available.  I downloaded and reviewed the release notes to find that this issue is fixed in 7.0.8 for HP 8440p and 2540p models.  I was able to perform the upgrade and it does in fact provide a solution.
