You would need the S30 to USB adaptor that will be releasing alongside the 10.1 and 8.9. There is no official confirmation yet that it will work with the 10.1v, but I'm pretty confident that it will.
You will also need Honeycomb 3.1, which enables USB host support. No release date for 3.1 on the 10.1v has been given, though pretty much everyone does expect 3.1 to come to the 10.1v somehow.
