Joseph, thank you for your reply.
I tried rebooting by completely shutting down the power before submitting the bug and it still persisted, however, a day later I just plugged out the wireless receiver of the keyboard & mouse and plugged it into another USB port and now it works fine.

I got mislead by this post: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/990870 I'll check the USB connector on my motherboard and see if the problem persists but this bug can be closed.
