Don't use a legacy, obsoleted, discontinued tree when writing patches. The mercurial tree is obsolete, and it is there just to preserve the tree history. Instead, you should use the git tree. The media_build tree[1] provides a feature similar to the old hg tree. [1] http://git.linuxtv.org/media_build.git The IR code has changed _a_lot_ since the last update in -hg. Basically, the entire support were rewritten, and now the protocol is (or should) be auto-detected. Douglas, It would be a good idea to write a patch for the legacy mercurial tree warning people about that. > > However, by incident I found those very keycodes are already defined in > the linux/drivers/media/IR/keymaps/rc-nec-terratec-cinergy-xs.c file, so > maybe the issue is just about loading it? > > 'lsusb' lists my device as > Bus 001 Device 006: ID 0ccd:00ab TerraTec Electronic GmbH > despite I do not own the 'HD' version of the device, your wiki > http://linuxtv.org/wiki/index.php/TerraTec_Cinergy_T_USB_XXS > says that ID corresponds to.
