Windows 7 Driver for SD reader- Latitude E5420

I'm in the same boat (same machine and OS). Put in my service tag number on Dell's support web site and 78 drivers come up, none of which belong to the SD media reader. Also tried letting the computer search the Internet for the driver, but without success. This is a result of formatting and re-installing Windows. I am actually missing 3 drivers for devices that the computer cannot recognize: Mass Storage Controller, SM Bus Controller, and an "Unknown Device".

Hi LandonDale,

The drivers for Latitude E5420 can be found in the links below:

http://dell.to/Or6yp9  for SD media reader.

http://dell.to/ULLue9 for the other missing drivers.

I hope you find this helpful.

Thanks for the quick response Kiran, but non of those drivers worked. The first two installed, but didn't affect anything. The third driver wouldn't install. It stalled while trying to locate a bluetooth device. I was able to find the correct chipset driver to remove the "SM Bus Controller" error, but the other two errors still exist.

Hi LandonDale,

The alternate drivers for Latitude E5420 can be found in the links below:

http://dell.to/TLhgc6   for Mass Storage Controller

http://dell.to/NUPQgi   for unknown device

I hope you find this helpful.

Kiran,

That's perfect. Those drivers worked and I am all set. Thank you for your help.

I have same problem with Landon but even I installed the driver, my laptop still cannot read SD reader. I aslo try with new version on Drivers & Downloads page, it doesn't work as well.

There's also an error after installing it.

Thanks
