Usb ports not working with GA-970A-UD3 and ubuntu 12.04

[tven]

I recently bought a GA-970A-UD3 mother board to use in a Ubuntu system, I'm a novice with using linux so I'm have a serious problem. I was able to install linux and can log in ok, but at no point is my USB mouse being detected, also no USB drives are being detected by linux. In the bios USB drives and my mouse are all detected and work as expected. This seems to be a problem with ubuntu not being able to use the motherboard correctly.

I am hoping for some advice in getting my mouse to work otherwise I am going to get really stuck.

1.open a terminal
2.type lsusb (without the quotes)
3.see if at least one item is listed.
The response should look something like this:

Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

Bus 002 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

Bus 001 Device 002: ID 8087:0020 Intel Corp. Integrated Rate Matching Hub

If lsusb doesn't list anything, then it's possible that you are missing some basic packages.

Hi,

Thank you for all your suggestions autotech. I found this post while at work today http://ubuntuforums.org/showthread.php?t=2111223 which exactly matches the problems I /was/ having. Reading though the posts lots of people where having success with editing the bios so that IOMMU was set to ENABLED. Once I did this and booted Linux all the USB and Net work ports began functioning correctly.

Thanks again for the quick responses and help.
