Blu-ray drive doesn't detect UHD discs

[febefe]

I have a Pioneer BD drive. Model is BDR-209D.

UHD discs are not detected with this drive + Passkey.

What can I do to detect UHD discs? Do I need a different drive or should Passkey work with all drives?

I don’t believe that drive supports UHD discs.
