It doesn't in any standard distribution, because it is still being worked on.
So far, we have most of the generic USB 2.0 changes applied to the hub code
(but not split TT, as of yet), and we have an EHCI driver that can do low/full
speed handoff, control transfers and bulk transfers. No periodic (isochronous
or interrupt) transfers yet, although some of the code is done.
However you can patch it into the -ac kernel series fairly easily, assuming
that you know a little about patching kernels and the like.
The driver itself is available for testing from the Linux USB CVS archive,
see: http://sourceforge.net/cvs/?group_id=3581 and
http://cvs.sourceforge.net/cgi-bin/viewcvs.cgi/linux-usb/hcd/ and please read:
http://cvs.sourceforge.net/cgi-bin/viewcvs.cgi/linux-usb/hcd/README?rev=0.5&content-type=text/vnd.viewcvs-markup
Hope this answers your questions, and let me know if you want to help out in
some way.
Brad
