Hey guys,
I want to tell you i found here a solution in order to make it work with debian 12.
I use debian 12 too and this dongle.
It works after manipulation of Starlight wrote in his post and the link post by WhyWontItJustWork is there i downloaded last week the archive for my architecture.
But the folders of the archive for all architectures are only executable.
Don't install the command line
curl apt.flirc.tv/install.sh | sudo bash
It doesn't work, i had try in vain.
So you can follow the solution found by Starlight and you will enjoy use the dongle and your remote control.
It's the only solution to make it works at this time.
