| Sarah Sharp is sponsoring an intern to work on the USB 3.0 host controller driver. The Linux kernel USB 3.0 driver was introduced in 2009, and works 10 times faster than USB 2.0 devices. The USB 3.0 driver still needs a lot of work, so there are plenty of small bug fixes that interns can tackle. If time permits, interns could also work on small to medium features. | If you are interested in being a Linux kernel intern, please: |

| = Getting Started = | The Linux kernel contains many data structures whose contents never change once they are initialized, many of which contain function pointers.
