I found solution.
it can be fixed in some other ways:
solution 1.) Disable "Always enable pre-boot USB support" in the policy->Boot Options
solution 2.) Update the BIOS version.
solution 3.) Disable USB legacy support in BIOS
This case was with DELL Latitude Laptop
As a side note - you mentioned you are ein the progress of going to 5.0 - please make sure you have right patch level :
The minimum supported version of ePO is version 5.0.1. There is no support for ePO v5.0.0.
The following minimums also apply:
- McAfee Endpoint Encryption for PC version 7.0 Patch 2. No earlier versions will support ePO v5.x.
My current spec is ePO5.0.1 and EEPC7.0.2
U have describe simillar issue but for DELL tablet (as i remember)
Anyway, it work for DELL Laptop too.
Don't you have to have the machine imaged with UEFI in order to be able to disable pre-boot USB support? Currently we are not imaging machines with UEFI and it cannot be changed without rebuilding the machine
I do not do any other things than i describe.
