I have pushed a bunch of code to the uhd repo and gnuradio next branch.
http://ettus-apps.sourcerepo.com/redmine/ettus/projects/uhd/wiki
-------------------------------------------------------------------------
USRP1 multi-channel support has been completed. Multiple channels can be
access through the new "single usrp" API which supersedes the "simple
usrp" API. The equivalent gnuradio blocks(uhd single usrp source and
sink), and grc wrappers have been created as well.
http://www.ettus.com/uhd_docs/doxygen/html/classuhd_1_1usrp_1_1single__usrp.html
The "simple usrp" interface is now deprecated but will continue to work.
In the single channel case, all API calls are identical; to switch any
code that was written for simple usrp, just change the include header
and instantiation to the following:
#include <uhd/usrp/single_usrp.hpp>
single_usrp::sptr sdev = single_usrp::make(args);
If you are running in GRC, just drag and drop the new blocks and swap
the connections. :-)

In other news,
UHD can now compile against pre-built libusb1.0 windows binaries:

Runtime operation has yet to be confirmed.
Thanks!
