I have just installed a fresh copy of Windows 7 Ultimate 64-bit SP1. I currently have 2 Data Interface with a yellow exclamation which means it's unrecognized and the drivers for it are missing.
I have installed all of the drivers found in this post on the dell forums:
Windows update has been unable to find the missing drivers for the device and I can't figure out what the device could be.
I have a Dell Inspiron 1525. What could the Data Interface be?
