Hi, There used to be a company called Miglia Technologies Ltd. in the UK, and the company was selling a product called Harmony Audio in 2004. Upon obtaining the product by chance recently and examining its internals, it was revealed that it utilizes Oxford Semiconductor OXFW970 for its communication function in IEEE 1394 bus. This patchset adds support for the model.
