I don't hold out hope that these type of USB remotes will work with Intel Macs with newer versions of OS X or not.
The one you link definitely looks like a remote that WILL NOT work with Macs despite the title.
The seller has not listed any specs to or info to show that this device will definitely work,with a Mac or not.
It's not a simple matter of just plugging this device into a USB port and it will just work. No.
As I stated earlier ,there were companies that made USB IR remotes for Macs that didn't have remote operation capabilities.
Most Notably, Keyspan made a few models of these that worked well with older PowerMacs and the remote was customizable.
Here's the one I still have and use with my old PowerMac G4 MDD. Works surprisingly well.
It still worked under OS X 10.5.8 Leopard using OS X 10.4.11 Tiger drivers.

You need proper Mac OS X drivers and software to use these. Without the correct OS X drivers and, possibly, software, these kind of remote devices maybe useless on a Mac.
Here's a newer version of the same style of USB remote re-badged by Tripp-lite( the company that bought Keyspan) that may work, also.

I am, relatively, sure and confident that these type of USB IR remotes will no longer work on newer Mac technology or on OS X 10.6 and up.
I think you are being stubborn, to your own detriment.
