Here's a summary of a recent series of tests I did per Intel's direction.
Is anyone using the USB 3.0 ports on this board with USB 3.0 external hard drives? If so, please post your experiences and include board version. I'm posting this because I can't believe that I'm the only one that has encountered this problem. USB 2.0 and USB 3.0 devices on USB 3.0 ports almost always have issues under all other conditions. USB 2.0 and USB 3.0 devices on USB 3.0 ports don't have issues when used under BIOS 2040 and MSConfig Diagnostic Mode. USB 2.0 and USB 3.0 devices on USB 3.0 ports don't have issues when used under BIOS 19. I'm being careful and limiting my statement to USB 3.0 external hard drives because those are the only USB 3.0 devices both Intel and I have been testing with.Ĭurrently, it's in the hands of Intel design engineers to try to figure out root cause. It may or may not be an issue on the -305 version. Intel has replicated and confirmed the issue of USB 3.0 ports and USB 3.0 external hard drives not working properly on the -306 version of the board. Since that posting I've done additional testing and follow-up with Intel. I've done extensive testing on this issue - you can see some of that here in Post # 29 of this discussion thread: IN ADDITION, the USB 3.0 ports on the DP67BG board (at least the -306 version) do not work properly with USB 3.0 External Hard Drives when a BIOS version newer than 1900 is used. The USB 3.0 port / USB 2.0 device issue still exists on the -306 version of the board. You can see that thread here:Īfter posting that discussion, I RMA'd my board (version -305) and received a new board (version -306).
In another discussion, I posted about issues I was having with the USB 3.0 ports not working properly with USB 2.0 devices.

Problems can arise when your hardware device is too old or not supported any longer. This will help if you installed an incorrect or mismatched driver. Try to set a system restore point before installing a device driver. It is highly recommended to always use the most recent driver version available. Print out these instructions for use as a reference during the installation process. The Taskbar should be clear of applications before proceeding. To ensure that no other program interferes with the installation, save all work and close all other programs. During the installation of this file, be sure that you are logged in as the Administrator or as a user with Administrative rights.

This driver also resolves the yellow exclamation point error that may appear in Device Manager as "Universal Serial Bus (USB) Controller" which indicates that a driver is not installed for that device. This utility installs the originally shipped version of the Renesas Electronics USB 3.0 Host Controller driver.
