Anybody know of a beta-driver for USB3 and a Z77 Intel chipset? (on a MSI mobo)

My USB3 is so sloow compared to same port in Windows 7. My daily backup of files, drawings and reports takes a LOT of time. This might be a windows 8 killer, if Intel and MS can't solve it.
 
Thanks, but that did not help. My problem is "only" performancewice. I.E. in windows 7 copy is done witn about 138kb/sec and in win 8 it is abot 41kb/sek. That is with Windows 8 Pro Upgrade downloaded image.
 
I believe its the lack of an Intel USB 3.0 Extensible Host Controller driver that is causing this issue. I have it as well. There are no drivers for Windows 8 yet.
This is why using the same hardware under W7 the speed is so much better.

As far as i can see we cant do anything about it until Intel release these drivers.

You're absolutely right. I can't believe Intel hasn't hasn't released a driver yet. I tested my USB 3.0 external drive and performance is down quite a bit compared to the results I got on Windows 7
 
Not even a beta-driver to be found anywhere? I think it is a really letdown for Intel not having this in place with launch of Windows 8. And now a month later ... well Intel is still sleeping.

Does anybody know of USB3 performance with an ATI/AMD chipset?
 
Windows 8 has native in-box USB 3.0 driver. Intel is not releasing a specific USB 3.0 eXtensible Host Controller driver for Windows 8.

We finally have our answer. I can't believe it. My Western Digital USB 3.0 performs worse in Windows 8

OK, that did it. Windows 8 is only for toy, when nothing else is going to happens from Intel.
My Samsung USB3 is taking even a higher hit in Windows 8 compared to win 7. And Intel don't want to do anything about it? I'm lucky to reach just 50% speed in Windows 8 compared to same drive, same port in Windows 7 (USB 3.0 that is).

How about AMD USB 3? Are they hit by Windows 8 also? (yeah, I know they don't have an Intel USB3 chip !!!!)
 
I'll test it on my AMD rig next time I boot it up

UPDATE: I ran the USB 3.0 drive on my AMD system and got the same results as I did on my Intel machine using Microsoft's driver ie: 120MB/s

Indeed yes, it is working. Still missing some performance but now it is down to under 5%, so that is really nice. How do we make Microsoft and Intel aware of that this is what we want?
Thank you very much, tw33k, nice of you sharing this info with us!
 
A very big thank you to tw33k for finding this fix. Its not perfect but its way better than we had before.

Shame on Intel for ignoring this, and shame on MS for not making better drivers, or at least letting the public know about this crippled feature.
What i don't get is Windows 8 and USB3 are supposed to be the way forward, the future, yet this OS cripples it.
 
Glad it's working for you both. If Intel isn't going to release something then Microsoft have to make it a matter of urgency to get their drivers working properly
 
I didn't realize I had an issue with my Intel USB 3.0 ports until I tried using my new USB 3.0 drive this weekend. I got a message that it wasn't usable due to a previous device failure, yet it worked fine in my one USB 2.0 port. 2.0 devices work fine in my USB 3.0 ports, too. I'm going to follow this guide and see how it goes. Thanks!
 
I'm happy to report that it worked. After 5 minutes of work, I am now able to use my USB 3.0 flash drive on my USB 3.0 ports on my Ultrabook. Previously, the device wasn't even recognized using the Microsoft stack.
 
I went to the web site to download the driver. It said for I7 processors 2nd generation only. I have a first generation, do you think it will work with that? I couldn't find one for 1st generation.

Thanks Clint

Update: It didn't work on my PC.:cry:

Intel® USB 3.0 eXtensible Host Controller Driver
Where is Intel® USB 3.0 Extensible Host Controller driver for Windows 8*?

Windows 8* has a native in-box USB 3.0 driver. Intel is not releasing a specific Intel® USB 3.0 eXtensible Host Controller Driver for Windows 8.

If you are upgrading Windows 7* to Windows 8, uninstall the Intel USB 3.0 eXtensible Host Controller Driver before installing the upgrade.

Operating System: Windows 8*

This applies to: Intel® USB 3.0 eXtensible Host Controller Driver

Just found this thread, was waiting for an Intel USB 3 driver for Windows 8.
My Intel USB 3 port, with the Windows driver, is a little slower than the Intel USB 2 port.
The VIA USB 3 port is almost twice as fast as the Intel USB 3 port.
Tested with ATTO.

Will try tw33k's fix.

Edit: It works.
Downloaded the latest Intel driver 1.0.7.248, made the changes, installed.
When checked in Device Manager it has Intel USB 3 driver 1.0.6.245.
Not going to complain, the Intel USB 3 port is about 1% faster than the VIA USB 3 port, huge improvement.
