XPS 8700 SD Card Reader Stops After Windows 10 Update
Recurring issue with Windows 10 updates, including the latest "creators" update, resulting in loss of connection with SD card reader even though the card reader light continues to flash. I've spent hours scouring the web with a huge array of solutions posted. I think in the past an updated driver from Dell solved the problem, but not so this time (card reader driver on Dell's site is two years old).
So taking a cue from a post regarding a different model, I checked the Realtek web site for its most recent card reader driver, which is dated 7/25/17, and it worked.
I'm posting this in the hope that others with the same issue will benefit.
