Unfortunate I am lacking bandwidth to help you more at the moment. I looped in some the most recent contributors to the rtsx driver, which I think is the one being used (I might be wrong here). Hopefully some of them may be able to help you. Kind regards Uffe > > > > # lspci -xxx -s 4:00.0 > 04:00.0 Unassigned class [ff00]: Realtek Semiconductor Co., Ltd.
