Some additional information:
The same symptoms appear on the original BIOS version 69 as on the new one version 100.
I might just try version 95, but I don't have high hopes.
UPDATE: I have tried BIOS version 95 and there was no change. Message was edited by: Deon Korb

I have come to the conclusion that these boards have a design flaw on them that Intel does not want to acknowledge.
I was sent a replacement board that exhibited the same behaviour. Three BIOS revisions and no fix in sight.
I am rather trying an ASRock motherboard.
Anyone trying the same, I recommend against using this board.
Seems to be that you are not the only person having this issue; however I would like to know which is the operating system you are using on the DH77DF motherboard?
Any news on this topic? Can the problem be resolved by updating the BIOS?
Maybe you should install windows7 once, before you can use the CIR Device under Linux.
That is an known Issue on other Intel Boards like dh77eb
Guys,please try BIOS 0110 for the Dh77DF motherboard. You should also check for updates to your respective CIR device.
