Very annoying USB problem w/ EP45-DS4. No USB 2.0 function.

post #1 of 3
Thread Starter 
I have a very annoying issue with this older LGA 775 motherboard: GA-EP45-DS4. Latest BIOS F10b.

USB 2.0 controller option is enabled in the BIOS, yet all USB ports are operating at 1.1 speeds. I know this for a fact because at the device listing screen after the post screen there are only USB 1.1 devices shown... and more importantly, I have tried plugging a mouse to each port and every time it was reported as being plugged to a Universal port. This is especially annoying because Device Manager shows 2 ready EHCs, so it's not a problem with Windows.

The two EHCs show the same location as the other Universal controllers, so obviously this means that the motherboard is not assigning the Enhanced function to the devices, hence operating at 1.1 specifications.

I have tried everything... optimized defaults, uninstalling and reinstalling all USB controllers, enabling & disabling various BIOS options... nothing seems to fix it.

I know it's a long shot, but if someone can somehow help me I'd be very grateful.

You say it's not windows. But since it's an older system, is it Windows XP?

If so, it needs Service Pack 2 or 3 I believe to get full 2.0 speed

IIRC...

Nah, it's Windows 8.1.

I also have another problem, which is that I have to restart the PC every day for the sound card to work... I guess it's just an old motherboard.

But nvm, hopefully I'll be upgrading to an i5 soon. happysmiley.gif
