Working O2Micro card reader driver for Dell Latitude E6530?

Has anyone found a *working* SD card reader driver for Windows 10 x64 for a Dell Latitude E6530? Whatever windows installs by default seems to be a dummy or stub driver. It shows no problems but doesn't actually work. Plug a card in and it makes the sound but doesn't appear in Explorer or anywhere else.

I tried Dell's driver for an O2Micro card reader for the Latitude E6520 (and others) but that one says EVERY card has to be formatted, or says a card needs to be inserted when attempting to open the drive with a card plugged in that shows up perfectly fine on any other computer.

WUMT didn't find a driver. There's more than one O2micro SD card controller chip model. How do I tell which one is in this model of laptop? Device Manager is of course not telling, because it would be to convenient for the user if it had such detailed information.

I recently setup a DELL Latitude E6420 for someone which also had an SD card reader. I suspect the system is fairly similar to yours. I could not get this to work either at first until I clean installed W10 Home and a Generic SD card reader was automatically installed by windows and it worked fine, reading and writing to the inserted SD cards. The O2 Micro driver was not needed.

Try removing all drivers and software for the SD card reader and let Windows choose again or deliberately force it to install the driver for a "GENERIC SD02G SD Card".

Note: You may well need to have a SD card inserted before you can actually see the drive showing up in Device Manager.

I manually installed the SDA Standard Compliant SD Host Controller driver and it works, up to at least a 32 gig. Microsoft's OSMicro driver *does not work properly* with the controller in a Latitude E6530, despite auto detection insisting that is the *best driver* for it.

Yep....that's how my old "Rocketfish" card reader for my PC from bestbuy works. I got this thing back in the Vista days and it had a driver for it. Since the move from Vista to 7, 8, 8.1 and now 10....it uses the generic driver as plug/play type deal. It never showed up in file explorer until I actually inserted a SD card in it. It works perfectly.....insert card, green light pops up and SD card shows up in file explorer.

I don't know if it's limited to 32 gig. Not going to try the 64 gig that's in my phone. The laptop is from circa 2013. Dual core Intel I7 3540m Ivy Bridge, 1080p LCD, nVidia 5200 NVS + Intel integrated video. Has 8 gig DDR3 but can go up to 16 gig.
