I had the 2.6 driver working nicely prior to the xend and subsequent xenbus changes now I'm updating to use xenbus. I have defined a higher level inter-domain communications API similar to the one described in this thread on inter-domain comms (my API is a bit different and I've only defined the bits actually required for my USB driver): http://lists.xensource.com/archives/html/xen-devel/2005-05/threads.html#00159. I've now ported my FE and BE USB drivers to this new API and I've just started implementing the API using xenbus and grant tables. I was hoping I would have it working this week but I think it's going to take a bit longer. I'm not intentionally working out of tree, I just wanted to submit something that worked and I've been playing catch-up with the xenbus changes. Harry.
