Hi,

I had added in my XenIntro Wiki page ( http://wiki.xensource.com/xenwiki/XenIntro) a simple code exmaple which demonstrates adding new device (backend and frontend) and triggering of probe() in a backend driver ; I am doing it not by using a python script , as Xend does, but by xenstore-write tool. This exmaple is far from being full, but it works with latest mercurial unstable version. Since that there were some posts in this mailing list regarding this subjcet (probing and backend/frontend devices) maybe some will want to take a look at it (especially as a way to bypass the python code, which is somewhat cumbersome).
