Where is it documented? Do the Xen developers / The interface definition is living in the Xen git repository for several years now: git://xenbits.xen.org/xen.git -> xen/include/public/io/usbif.h It is used e.g. in SUSE's xen kernel since 2.6.18. The differences between the Xen version and the one I've posted here are only style and name space related. > maintainers agree with this interface and code?
