Steve, Krystian in Poland has tackled GPIO on the RaspberryPi. I can fish up his repos if needed...

That's going to be a bit much to chew off for a student project. USB
is a non-trivial mess of pain and frustration, even for the
experienced. If someone is getting started with driver work, the most
successful path will likely be implementing a simple part (even if
it's an old one). Ethernet and UARTs come to mind - they tend to be
the simplest. I think at one point there was a call out to get GPIO
working on the Raspberry Pi - that would be a good summer project if
it hasn't been done already. GPIO can be a lot of fun, especially if
you have a couple of protoboards laying around.

Anyhow, when it comes to GSoC it's far more important to focus on
attainable goals - it's a lot more fun for the student (and the
mentor) when something working comes out at the end.

HTH,

Steve
