The dongle is recognized as a keyboard by the computer and an independent program to program the (associate an IR remote control code to a combination of keyboard keys). So use is greatly simplified: no more problems lirc driver on Linux, and utilities endlessly under MacOS or Windows. So I highly recommend the purchase. I just removed one star because the application to set the dongle is a bit temperamental MacOS, especially when we want to delete a key combination (you have to try several times). Nothing serious in any case since the contributions of the solution.
