This is (most of) the usb2 debug console code ripped out of
Uwe's version of yh_rest_of_patch.patch (13.02.07 - [PATCH]
Rest of huge MCP55 patch).

I dropped a lot of stuff, like broken indenting, removed copyright messages,
and this printk_ram_* stuff (what the heck is this supposed to be)

This codebase is really a mess. Further tarball contributions without a
_CLEANED UP_ patch will be denied, especially if they are not from an up to
date svn tree.
