Windows 7: USB 3.0 Extenal Drive keep dropping

Hi,

I saw so many problems about USB 3.0, I am not sure if this is a new one.

I have install a 3.5" harddisk on a USB 3.0 external casing, when I plug it into the USB 3.0 port, it come up a while (like 30 seconds) then disappear, and never to be seen again. If plug into a USB 2.0 post the same thing happen. The following are my PC configuration:

Windows 7 Pro x64 SP1
Asus P7P55D-E Pro
BOIS version: 1602
USB 2.0 : Intel 5 Series/3400 Series Chipset, Driver version: 9.1.1.1020
USB 3.0 : Renesas Electroincs USB 3.0 Host Controller, Driver version: 2.1.28.0, FW: 3025
External casing is HUR1-SU3S2 with single WD20EARX harddisk.

In the begining, I thought it is the problem of the external casing, but when I tested in a laptop running Windows 7, it is working fine on a USB 2.0 port.

Help someone can help me on this problem.

Thanks in advance.

Could be the chipset inside the external enclosure causing the problem.

What brand and model number of the enclosure would help determine if that is the problem.

EDIT: OK, tracked the enclosure down. It is a RAID enclosure but can be setup for a single drive. I would image that you should have a way to set it up with the included software for non-raid.

Just my thoughts on what the problem might be.

Hi,

I have done that with single disk, non-raid, it is not work on the Asus board, but it is working on a notebook Windows 7 x64 on a USB 2 port. I have also change another external casing, USB 3.0, single disk casing, same problem, but works on the notebook Windows 7 x64. I guess it is the Renesas driver on the Windows 7 x64. I had also installed the latest driver, but no luck to get it to work.

Thanks.

Just out of curiosity, did you add a PCIe x1 USB 3.0 adapter card to your machine, or did it come pre-installed?

I added one (from Transcend, but it's really Renesas) into both of my machines (which both write to an external Verbatim USB 2.0/3.0 drive... which is actually a Samsung SATA drive in the external USB enclosure) and have no problems (although I am using an older Renesas driver 2.0.32.0 which came on a little CD with the card. No problem whatsoever on either machine.

Now for sure you have to connect external power to the card (via Molex plug) as the PCIe bus does not provide the power required to drive the USB 3.0 connection. Do you have external power going to your USB 3.0 adapter card?

Doing a little searching...

Looks like there might be a firmware upgrade to address this problem. But I don't know if the affected hardware is what you have.

Read this thread.

Hi,

Thanks for the reply. The MB came with 2 USB 3.0 port, NEC Chipset (from the website), it is not working so I bought another PCIe USB 3.0 card, thinking it might use another chipset, it end up the same. So both of them are not working.

Question:
Is there any other PCIe USB 3.0 card out there not using NEC chipset? I just go to get one and solve my problem, please help.

Thanks.

Hi,

The firmware is already in 3025. Thanks.

This is the card I bought. For $15 how could I go wrong? I bought two, one for each machine.

But it still seems to be a Renesas product, and as I said uses an older driver version from December 2010. Never did any firmware upgrade, and checking for newer drivers says I have the most current for the card. I have no complaints.

Works perfectly for me, in both machines.

Hi,

The card you got look like the one I bought, but it doesn't work. Thanks.
