I am having a very similar problem to this on my ASUS UX31A, which uses an Intel HM76 chipset. I've written up a help request for ASUS, which I'll repeat here:
First of all, thank you to anyone willing to take the time to help me out.
I recently tried to create a system image of my laptop on a Western Digital My Passport Essential via a USB 3.0 connection. The image gets about 1/3 of the way done, and then I hear the "device disconnected" chime go off (like if you unplug a USB key or device), and I get a message saying the backup failed because Windows can no longer find my external drive, which tells me that the drive is disconnected. The drive re-connects right after, as AutoPlay opens up for the drive, but by then the backup has already failed.
This only seems to happen with portable external hard drives (powered through the USB port), as I've been able to make system images using two external hard drives (one of them a WD MyBook) that have their own power supply plugged into the wall. I did some research, and it seems this is a common problem, not just with ASUS laptops, where the hard drive draws too much power from the USB port and disconnects (or something like that), which would explain why the external drives with their own power sources work.
I found an update for Windows 7, KB976972, that addresses an issue very similar to this; however, this update only works with nVidia chipsets, and I've been informed I'm running an intel chipset, and thus the update doesn't install on my computer (I get a message along the lines of "This update is not for you computer").
I've been to the ASUS download site for my laptop here:
...and have downloaded and installed all the recent drivers, as well as upgraded the most recent BIOS version 212.
Furthermore, I've run ASUS live update, which detected no new updates for my computer, suggesting to me all my drivers are up to date.
I'm running Windows 7 Pro 64-bit edition w/ SP1, which has been fully updated (Windows Update detects no new updates).
The WD My Passport I tried to use is also fully up to date, with the most recent firmware and driver.
I don't know if this is a WD problem, Windows 7 problem, Intel problem, or ASUS problem, but I'm just trying to cover all my bases here.
Thanks again for the help, and looking forward to some answers!
Can you please be more specific about the BIOS update that fixed this issue? Is it available for the HM76?
I exactly have the issue. Any luck with your problem. I could get the read to work from the USB 3.0 port after upgrading mother board BIOS to BLH6710H.86A.0160.2012.1204.1156 and Renesas Driver to 184.108.40.206 and Firmware to 3034.
But the moment I write to the USB 3.0 external hard drive [Seagate expansion 1TB], disconnects and reconnects. Guess there is no solution to this issue. The same USB 3.0 ports works fine for the USB 2.0 devices and my new USB 3.0 hard drive works fine on USB 2.0 ports.
Also I don't see any way to get support from intel on this issue. If I don't get to solve this, surely I'll change my motherboard will moving out on intel [MB and processor]
I am sorry to hear you are having problems but let me help you.
Based on your description, I see you have done several steps that are excellent such as updating the bios to the latest and doing the firmware updates.
I recommend you installing a firmware update for your drive since it is constantly disconnecting. Since you have done the steps before and If the issue persists after updating the firmware I recommend you contacting your local support so they can check the system and replace it if necessary.
Thanks Kevin for replying, appreciate that a lot. Will try to update the
hard drive's firmware, although seagate's website doesn't list an upgrade for
my drive. They have firmware search based on serial number and part number.
But you never know, thanks anyways. It seems USB 3.0 is flaky and many
people reported some issue or the other, will keep trying to fix it else be
content with usb 2.0 for now :-(
I had the same problem. My mother board is also DH67BL with the 0156 version of BIOS. At first I updated the BIOS to version 0160 but this has the problem os "CMOS CheckSUM error" and I come back to 0156.
For Renesas 3.0 the version of driver was 2.1.28 but I I download the driver update from "http://www.station-drivers.com/index.php/downloads/Drivers/Renesas-Nec/USB-3.0/ " 2.1.39 and the firmware update, the last 220.127.116.11 and when I start my computer all my devices at USB 3.0 are detected.
Before I have a uEye camera and when I start the computer always appear like Unknown device, not is working properly.
OH no again the same problem, it is working till I turn off the computer and switch off the main power of mother board, and again the same problem. Doesn't recognize my camera Ueye model UI-324xCP.
I think maybe is a problem with the power internal from motherboard, because when I plug off the camera and plug on again is recognized, and if I restart the computer still recognized, but when I turn off and switch off the power while for 5 o 10 minutes and turn on the computer , again show "Unknown device".
I have another external PCI board controller, also by Renesas usb 3.0 , and if the camera is connected in the external pci controller always works, so what it really the problem? something with internal power management at mother board? I don't know. Also if the same camera is connected in a USB 2.0 at the same board always detected fine.
What I need, and suppose everyone with a similar problem than me, is that INTEL fixed this bug on their mother board because there is a lot of people with this kind of problem, maybe is just that the controller need a new driver version, or firmware...
It is too bad to hear it failed again. I would recommend you again doing the BIOS update and updating all other drivers and in the worst case reinstalling the Operating System.
You can also contact our Support team for them to help you checking the unit and replace it if necessary.
