# hxoctkl: reconstructing HyperX Alloy Origins Core profile writes

> hxoctkl reconstructs USB HID profile control for the HyperX Alloy Origins Core tenkeyless keyboard and writes persistent per-key RGB animations from Linux. Its protocol notes specify 64-byte reports, command opcodes, colour-buffer packing and the upload and commit sequence. The research used device queries and one NGENUITY USB capture, and builds on OpenRGB's earlier findings about colour-buffer packing.
