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.
