We have been testing the same NUC model with the CIR and remote control model RC1534001/00 and so far it is working just fine.
As far as I understand you installed the driver from the bundle but for troubleshooting steps, please try this driver:
Can you also test another Remote Control?
Thanks for responding so quickly, Kevin. I have actually tested two remotes which are known to work on my old HTPC (with a USB IR receiver). I have a standard MCE remote and a Logitech Harmony remote with the appropriately programmed IR codes. The box seems to do nothing. I assume there is no IR LED or anything that indicates it is receiving an IR signal?
I will give the troubleshooting drivers a try. What's different about them, is it just another possible driver or does it have debugging tools?
Not suggesting it's the case, but at what point do we say, hey this may be a hardware problem with the IR sensor? I tried doing some googling but the only issues I've seen people have with IR is with Linux distros like OpenELEC. Seems it "just works" for everyone using Windows 7 and the provided driver.
Have you tried with a clean installation of the Operating System? If you have tried this, I recommend you contacting our phone support for them to help you with a possible replacement:
