MCAfee Drive Encryption doesnt boot when keyboard/mouse/dock is connected to the computer

Hello, i`ve got some of Lenovo stuff like L470, T480 which when they got connected usb mouse or keyboard Drive Encryption doesnt want to show the screen of login, its black with no response from McAfee or computer. When i disconect the mouse/keyboard and restart the computer i`ve got a Drive Encryption screen like i had to have. Sometimes when i`ve got connected DOCK (f.e. USB-C Dock) or minidisplay to hdmi conventer it also doesnt show the login screen.

I tried with dell/lenovo/microsoft stuff (mouses and keyboards).

What I should do to resolve it ?

Thanks 🙂

It sounds like a problem either with the laptop/dock model or a PBFS issue.

Did you enable USB support at PBFS level?

In case it is not, you need to turn it on but it will require either Emergency Boot or decryption/encryption to include it in the PBFS.

Also it could be an issue with the laptop firmware - Legacy BIOS or UEFI. Make sure you have latest version installed and you can try reimaging with the opposite firmware type.
