X61 Right Side Usb Not Working
The two USB ports on the right side of my laptop do not work. The one USB port on the left side does. I found a solution in ubuntuforums by adding irqfixup to the kernel arguments fixed it.
sudo sed -i.bak -e 's/\(^# kopt=.*$\)/\1 irqfixup/g' /boot/grub/menu.lst && sudo update-grub
