Latitude e5420 can't find "Mass Storage Controller"
I did a fresh install of Windows 7 Pro 64bit and have all the drivers loaded, I think, except one:
Mass Storage Controller
Can't find the driver, don't know what it is. I've installed the chipset driver, the ATA driver, etc. Still it shows as not found.
Any tips or leads would help.

Hi benhenny,
You might need to install the O2Micro OZ600xxx memory card reader driver from link: http://dell.to/Zh2RDQ
Please reply for further clarifications.

Hi ZatanX,
'Unknown Device' in 'Device Manager' indicates that there is a device that is not working correctly. To fix this issue, you might need to install an updated driver for the device. For more information on identifying unknown devices from 'Device Manager', you may refer to link: http://bit.ly/b4PO3r
