The USB error could be that the USB 3.0 driver did not install correctly, you may want to try installing it again:
Besides the basic parts needed to set up a computer, do you have any other device connected to the motherboard, such as video card, wireless card, USB keyboard, mouse, etc?
You can also try updating the BIOS of the board to the latest version available https://downloadcenter.intel.com/SearchResult.aspx?lang=eng&keyword=Intel%20Desktop%20Board%20DZ87klt-75K
Run the Intel® Driver Update Utility just to verify everything is up to day.
This is the latest Chipset driver; please check if this is the one installed on your system:
Chipset: Intel® Chipset Device Software for Intel® Desktop Boards
Thanks for the reply, and I went through the steps you outlined above (already had the latest USB 3.0 driver as well as the chipset device software), but no luck. The error is actually indicating a PCI Express device is not properly installed (driver is missing). Again, this is a nuisance rather than a show-stopper, but it would be nice to get it resolved.
Please do the following:
1. go to “Device manager”
2. right click on the “USB Input Device” (with yellow tag)
3. choose “properties”
4. choose the “details” tab
5. Then, under property please choose hardware Ids.
Please send me a print screen with that information.
Please do the same thing with the “Base System Device”
