You could try this driver: https://github.com/josch09/ampe_stor. From the code, it seems supporting AU6601, AU6621, and AU6625, but it's not working on my envy 13 ad110tu (AU6625). It can detect the card, and get the capacity, but then many errors will occur and finally the reader dies. Maybe it will work on your device.
