Awesome, glad that did the trick. Long story, I left NVIDIA a few months ago to continue flirc full time in September. Reached out to my old team mates to find out exactly what button mappings they were using. They weren't using HID keyboard keys, but another USB page called Consumer for the direction pad and select. 0xC for the consumer page, and Menu Up/down/right/left/select. Once we realized this, I needed to update the GUI so that it sent down those specific keys for pairing rather than the keyboard ones. Previously, select was 'return'.
