I can confirm the bug with the ASUS Formula V and Ubuntu 12.04, amd64 kernel 3.2.0-27. Upgrading the BIOS to 1503 solved the issue for me. Asus indicates that the BIOS "improves USB compatibility".
Note that upgrading the BIOS will require you to re-install grub-efi because NVRAM is erased. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/859137 Title: Motherboard AMD 990FX/SB950 usb don't work To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/859137/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
