Guys, for me the Genesys driver exhibited the same behavior, and I found that if I inserted the SD card, then ejected it, and inserted it one more time, the SD card would mount. This works consistently.
But, that is annoying, so I went looking for a better solution.
As I have posted many times, the newest drivers are available via new product releases, and the G501 is no exception, there are several new drivers useful in the G750/G751, and one of them is a newer Card Reader driver:
G501, Windows 8.1, Card Reader section, Realtek Version V6.3.9600.21255
http://support.asus.com/download.aspx?SLanguage=en&p=3&m=G501JW&hashedid=uv3gzPnU54cTZC6YI just uninstalled the Genesys driver and installed the Realtek driver, and now the SD card mounts first try every time
🙂The only difference is now there isn't a fancy SD Icon for the drive, it is just a plan Icon.
Please let us know how it works out for you
🙂
