Hello Roshan,
I understand that you are having connectivity problems when using your USB 3.0 devices.
In regards to your question, we had similar problems reported and have been fixed with a BIOS update.
Regards.

Hello,
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:
Hello,
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:
http://ca.asus.com/en/Notebooks/Superior_Mobility/ASUS_ZENBOOK_UX31A/#download
...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?
Thanks!
