SD Card Reader Error
I’m running Ubuntu 16.10 on an Acer Aspire V5-571P. I’m trying to use the built in card reader to read a micro SD card (that I know is working correctly).
Ubuntu will not recognise the card and I am getting the following message from dmesg
[11970.123839] mmc0: cannot verify signal voltage switch
[11970.259430] mmc0: tuning execution failed: -22

In case it can help lsusb returns:

02:00.0 is my card reader If I’m right.
So all in all I think Ubuntu knows there’s a card reader there but cannot read from it ( no drivers? ), anybody know what I have to do to get this working?
