The ECS website describes the USB support on this board as "4 USB ports on back of motherboard" and "two USB 2.0 port headers on motherboard". Its got the 82801G chipset and usually the OS loads a USB Enhanced Driver for the 27CC port and you've got high-speed USB. I cannot get it to load the enhanced driver so my front panel ports are running at low speed. Any ideas?

TIA

Which OS? Most driver installs tell you to upgrade to service pack 2 for XP or any version of vista to get USB 2.0 funtionality. It is built into the OS at those version and the OEM drivers usually conflict. In the past the ECS auto driver install would tell you this but I have not tried a G31. ECS also usually really wants you to do those intermediate reboots and not skip them during their auto install. Do your rear ports show up as 2.0?
 
It could be your case USB ports are only USB 1.0. If the back works as 2.0 then your case is made of old crap and is the limit. If the case plugs on the jumpers with a 4 pin its only USB 1.0. If it has a 9 pin plug then they are 2.0.
 
THanks for your replies. I've tried the mobo with XP SP2 and Vista Home Premium. The headers on the mobo are the ten-pin with one pin blocked as a key. It has all the appearances of a USB 2.0 mobo but I cannont get either OS to load the enhanced USB driver so they don't think it is.

I'm wondering if I just got a bad board??
 
I have the same problem as joepaisley, but I had got USB 2.0 working. joepaisley, you need to go to the bios menu, and go to intergrate peripherals to disable Legacy USB. I had done it and it worked for me, hope it'll work for you. :)
 
I'm having this same problem with USB 2.0 support on ECS's G31T-M motherboard. I've tried blackbyron's advice, but that didn't seem to do anything for me. I'm running Windows XP Pro 32-bit and I've tried both ECS's official chipset drivers as well as Intel's generic G31 chipset drivers. If anybody can think of something else to try, I'd love to hear it.

Thanks in advance.
 
Things to check:

- Install Service Pack 2 for Windows XP at minimum
- Enter BIOS, make sure USB 2.0 support level is set to 'High Speed', not 'Full Speed'
- Uninstall USB controllers from Device Manager, restart and let Windows install the best driver
 
tcsenter, thanks for the advice. I'll look for that BIOS setting and make sure that's not an option I'm overlooking. I might have thought full speed to mean USB 2.0 speeds, honestly. Those two terms sound much the same.

I'd already tried your other two points, so I'll go give this a shot and report back.
 
Okay, I looked for a setting to choose between "High Speed" and "Full Speed" for USB in the BIOS and there is none to speak of. I think I'll just have to pick up a PCI card for USB 2.0...
 
Sir, if you are still having an issue with this motherboard, please download the latest BIOS update for G31T-M here:

http://www.ecs.com.tw/ECSWebSite/Downloads/ProductsDetail_Download.aspx?detailid=812&DetailName=Bios&DetailDesc=&CategoryID=1&MenuID=6&LanID=0

Choose the latest one available (at the time of this writing, Version 09/01/07, Release Date 2009/01/14)

I have an exactly the same motherboard you have and had the same issue. I took the bet and flashed its BIOS today after taking a deep breath, and when rebooted, the USB 2.0 ports are suddenly recognized.

As always, please don't forget to install the chipset driver that came with your motherboard (or can be downloaded at the same website above).

I hope it helps everyone who stumbled upon this page.
