So fun fact...
Still having intermittent CardReader issues a month later, so I went to the support site to see if there is a new driver (just in case) and LOH-and-BEHOLD there is a driver from January 15 for the Realtek CardReader.
AWESOME! New Driver!
Except... Probably not.
Because I started having this issue back in April? So why is there a new driver listed as new as of January?
Ahhhhh...
Realtek CardReader Driver
See, I started having this issue back in April, so I tried to download latest driver (like many of us here) from the support site and it was listed as:
Realtek CardReader Driver v6.3.9600.21261 (A00) October 24, 2014
Which is now the driver version for the "New" driver last updated Jan., 15, 2015
Tried to install it anyway and yeah.
STILL EPIC FAIL.
And no one at Dell really seems to give a ***.
So keep that in mind if you are thinking about buying one of these...
