Now if Google search is correct the vendor id for this device indicates this is a Realtek (v024C) WLAN (c07) device. So what makes you say its linux id is 02d0:a9a6? In upstream linux I do not see any SDIO device drivers in realtek folder. Maybe Larry can provide clue/hint if a driver for this device is publicly available somewhere. Regards, Arend
